Key Differences Between Standard and Intrinsically Safe Torches

NS.jpeg

Hazardous Environments

Intrinsically safe torches are rated and certified for use in explosive atmospheres and hazardous environments where even the slightest spark can result in an explosion. Standard torches have no consideration for limiting sparks and are extremely dangerous to use in a potentially explosive atmosphere.

Body Materials

Standard torches are generally made from a low-cost ABS (acrylonitrile butadiene styrene) plastic. In contrast, intrinsically safe torches are made from very costly materials like Polycarbonate/ABS Alloy with permanently static dissipative UV stabilized additives. These additives dissipate static electricity that can build up on the surface of the light to prevent sparks and cost twice as much as standard ABS plastic. Additionally, IS torches must posse unique design features to contain battery leakage and venting for gases produced in the event of a battery malfunction.

Lens Materials

Standard torches are traditionally made out of transparent polycarbonate plastic. Intrinsically safe torches also use transparent polycarbonate but require an additional (and costly) special coating that dissipates static electricity.

Circuitry

Intrinsically safe torches require professional electrical engineers to design and develop circuits specifically created to meet the requirements necessary to pass the strict certification levels for an intrinsically safe rating. This is achieved by designing circuits that prevent or limit spark energy through the use of fuses, redundant circuit paths, diodes, and other components. Standard torches have an on/off switch.

Special Fasteners

Because intrinsically safe torches are rated for use in hazardous and explosive environments, they must remain sealed in and around those areas. This requires that torches not be opened to change batteries even by accident while in a hazardous environment, and thus, a special retention screw or "special fastener" is used to keep the light from being opened. A standard torch is easily opened, usually by unscrewing one end of the light.

Because of the knowledge and expense required to engineer IS-certified products, a limited number of companies can achieve this. Nightstick is a global manufacturer of over 50+ Intrinsically Safe professional, portable LED lighting products. Locate a dealer near you at www.nightstick.com

New flameproof housing supports hazardous area use for key AMETEK Land temperature measuring instruments

 Image of LWIR-640

AMETEK Land, the world's leading manufacturer of monitors and analysers for industrial non-contact temperature measurement, has increased its support for customer applications in hazardous areas with two new housing enclosures.

 The new EXSH1 flameproof housings have been developed for use with the EX SPOT pyrometer range and LWIR-640 thermal imager and are approved for operation in hazardous areas.

 Manufactured from 316/316L stainless steel and highly resistant to corrosion, both enclosures have a certified temperature range of -40 to +70 °C (-40 to 158 °F).

 Ingress protection to IP66 and IP68 means that they can be exposed to dust, water immersion and high-pressure water jets, making them suitable for use in almost any application in the harshest of environmental conditions, including those where explosive mixtures are present.

 The housing has a gridless design, allowing an unobstructed field of view, and is certified for use in areas with dust and gas hazards. Additionally, the enclosure does not require purge air for safety.

 The EXSH1 EX SPOT housing is designed for use with the EX SPOT range, a family of fully-featured, high-performance pyrometers for fixed, non-contact, infrared spot temperature measurements.

 EX SPOT pyrometers are available in a range of operating wavelengths, temperatures, and process requirements, and the new housing will enhance their capabilities in continuous annealing lines, semiconductor growth, and applications in the hydrocarbon processing and chemical industries.

 The EXSH1 LWIR housing has been created specifically for the LWIR-640 thermal imager, a long-wavelength instrument providing measurements between -20 and 1000 °C (-4 and 1832 °F) in three ranges with a choice of different optics and lenses.

 The LWIR-640 measures and streams live true-temperature images at up to 60 frames per second, providing high-precision temperature measurements and thermal profiles to continuously control, document, and visualise industrial processes.

 The new housing protects the LWIR-640 in applications including flare stack monitoring, critical vessel monitoring, storage pile monitoring, and operations within the hydrocarbon processing and chemical industries.

 With ATEX, IECEx and UKEX certifications, the housings comply with multiple international standards. This means that a common specification can be used for worldwide applications, greatly simplifying the task of specifying and quoting the product.

 A range of accessories is available for the housings, including various mounting brackets with pan and tilt adjustment, a sun shield for outdoor applications, and a spoolpiece adaptor. An environmental protection tube is offered for the LWIR housing, for flare stack applications, while further accessories for the EX SPOT housing include purges and a vertical mounting stand.

 Derek Stuart, Product Manager, said: “The EXSH1 housing allows customers in many new industries, including hydrocarbons and semiconductors, to benefit from the accuracy and reliability of AMETEK Land’s thermometers and thermal imagers.”

Making packaging that doesn’t cost the Earth

pl.jpeg

Globally, companies are seeking opportunities to reduce waste and the carbon footprint of their products. This has increased demand for environmentally responsible packaging, and the manufacturing company Futamura has become the world’s largest producer of sustainable cellulose packaging films, including their leading NatureFlex™ range.

The production of sustainable films requires precise monitoring and control of process conditions. Highly accurate temperature and humidity measurement is therefore essential, particularly during the film drying process and when finished products are stored.

Futamura UK uses Vaisala measurement equipment across their site, including Vaisala HUMICAP® humidity and temperature transmitters HMT360 in their coating towers inside their conditioners. The coating towers contain solvents which are flammable, so the products used in these areas must be certified for the Ex environment. The Vaisala HMT360 transmitters, now superseded by the ATEX-certified HMT370EX, are intrinsically safe, making them ideal for use in hazardous areas such as these.

Vaisala measurement instruments can also be found on Futamura UK’s casting machines, installed in the dryer ducting, measuring humidity and temperature. The Vaisala humidity and temperature meter Series HMT330 is designed to provide highly accurate measurements in demanding industrial applications. These transmitters control a valve which manages the amount of steam that goes into the dryers, allowing the humidity to be maintained at the drying set-point needed for each type of film. Moisture content is a significant factor in the properties of the final film, so accurate control is important to ensure product quality and minimise waste. The HMT330 is an older model, so, seeking to future-proof their measurement instrumentation, Futamura contacted Vaisala for advice.

A member of Vaisala’s technical sales team therefore visited Futamura’s UK site in Wigton, Cumbria to demonstrate the benefits of switching to Vaisala’s Indigo platform, and to discuss the options with Electrical Engineering Chargehand, David Carr, and Technical Engineers David Mansergh and Chris Reid.

“We described the applications for the HMT330 series instruments and the Vaisala representative suggested we try the Indigo520 display with a relative humidity and temperature probe HMP5,” explains David Carr. “We were more than happy with the suggestion. His vast product knowledge and expertise in engineering and process systems was a huge benefit in the decision-making process. He also went through the calibration process and explained how to set up the equipment with our electrical engineers. Vaisala’s service and support have been first class – they have gone above and beyond to help us.”

The Indigo520 can connect with two separate probes simultaneously and has a simple, clear, intuitive touchscreen display. Futamura particularly appreciates the screen size and easy-to-read graphs, as well as the ability to swap out probes for calibration. It has also been advantageous that the new HMP5 probes work mechanically in the same way as the previous devices, with which they were already very familiar.

The key benefit of using Vaisala’s measurement instruments in Futamura’s manufacturing process is that they enable accurate control of the production process, which ensures consistent product quality and reduces waste.

Summarising David Carr said: " Futamura has been using Vaisala measurement instruments for many years helping us ensure the quality of our sustainable packaging films, and we will continue to do so in the future. When you find products, and a company, that you can trust, it makes good business sense to continue the relationship. As a plant we like to standardise because it makes spares management and equipment replacement simpler. It’s safe to say that Vaisala is our brand of choice because of product reliability and ease of installation and operation."

The Importance of Auto Ignition Temperatures in ATEX Fan Selection

Axair.jpegATEX protection is all centred around preventing an explosion from happening when there is a presence of combustible dust or flammable gas, this means considering all potential ignition sources. When looking at sources, most people will look for sparks and flames as an obvious risk, but the gas or dust properties themselves are an important aspect to protect against.

One of these properties is their temperature characteristics. Flammable gases have specific ignition temperatures, known as autoignition temperatures. These temperatures represent the minimum temperatures at which a gas mixture will spontaneously ignite in the absence of an external ignition source such as a spark or a flame. As an example, the auto ignition temperature of hydrogen air or hydrogen-oxygen, is from 510 – around 584’C.

Let’s consider the principle of hot surface ignition – lots of processes, such as combustion, will utilise a gases auto ignition temperature to ignite a gas on contact with a hot surface (often a coil, thread, plate etc). This works as the high temperature of the surface transfers heat to the gas, raises the temperature to its auto ignition point, igniting, and sustaining combustion. Great for purposeful processes but when this is not considered when handling potentially hazardous gases, this can be the cause for the explosion.

The principle of hot surface ignition, and the avoidance of auto ignition is handled with surface temperature limitations. ATEX fan selections consider the maximum allowable surface temperature of fan motors that come into contact with these potentially flammable gases and dusts in hazardous ATEX environments. This concept is known as maximum surface temperature. It’s important to note that maximum temperature limitations are not in place primarily for the prevention of hot surface ignition, the main principle is to protect the motor components themselves to ensure their safe operation by preventing excessive heat build-up, but will also prevent the fan and motor from becoming a source of potential ignition by keeping temperatures below any auto ignition temperatures.

For those of you who are unfamiliar with the make-up of an industrial fan suitable for potentially hazardous environments, ATEX fans are constructed and classified in two parts, one label that explains the motor classification and protection, and secondly a rating for the overall fan construction including the casing, impeller, and materials. Part of the motor classification shows the end user the maximum surface temperature that the motor is limited to reach to prevent component getting so hot that it initiates the auto-ignition temperature of the surrounding flammable substances.

Your fan supplier should always ask for your hazardous area classification information, this will inform them of the gases or dusts present, their presence to determine the ATEX zone, the temperature limitations that must be considered, the materials required to ensure longevity and safe operation and the level of ATEX protection required from electrical components such as motors. Under DSEAR and ATEX legislation it is the sole responsibility of the end user to conduct or contract a hazardous area classification. Suppliers will not be able to supply equipment for hazardous areas without this information from the end users.

Why is ATEX certification needed in water treatment?

It is generally understood that all equipment for use in hazardous locations such as flour mills, coal mines, petrochemical plants and fuel transfer facilities, needs to be “intrinsically safe”. In other words, incapable of igniting an explosive atmosphere. However, some not so obvious hazardous locations include water treatment plants, tunnels and underground passageways or any location where a build-up of naturally occurring flammable material (such as methane or dust) could occur.

Wastewater pumping and treatment facilities, for example, emit flammable gases and vapours. These emissions come from substances that the wastewater could be carrying (e.g. oils, solvents or fuels from accidental spills) and from anaerobic digestion of organic matter (producing methane and hydrogen sulphide). According to NFPA 820 (Standard for Fire Protection in Wastewater Treatment and Collection Facilities) most pumping stations, spaces and buildings that make up a wastewater treatment plant must be considered hazardous locations.

In many of these hazardous locations there is a requirement for condition based monitoring (CBM), for example by monitoring the vibration of rotating machinery to predict failure. Particularly in the water treatment industry, the consequences of an unexpected breakdown can be catastrophic. In the event of pump failure, wastewater can back-up and overflow, resulting in accidental discharge of untreated sewage into water courses (rivers, lakes and oceans). This has led to water treatment companies being fined literally millions, to say nothing of the environmental damage!

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require employers to control the risks to safety from fire, explosions and substances corrosive to metals. This entails compliance with BS EN 1127 (Explosive atmospheres - explosion prevention and protection), which in turn requires that any electrical equipment used is intrinsically safe and complies with BS EN IEC 60079. Hence any CBM equipment needs to be IECEx/ATEX certified for use in hazardous locations.

Affordable intrinsically safe condition based monitoring

Intrinsically safe devices typically cost many times more than their non-intrinsically safe counterparts. This is mainly due to the increased manufacturing costs (e.g. additional safety components and encapsulation) but also due to the high cost of the required testing and certification. Test Products International (TPI) believes it has broken the ATEX cost barrier with the TPI 9080Ex vibration analyser, priced at a very affordable £3,500. IECEx and ATEX certified for use in Zone 1 and with North American approval for Class I, Zone 1, the TPI 9080Ex is certified for use in hazardous locations anywhere in the world.

The TPI 9080Ex is supplied with an industry standard (IEPE) intrinsically safe accelerometer and offers on-meter analysis for the detection of machine faults such as unbalance, misalignment, looseness and bearing wear. The TPI 9080Ex features colour coded alarm levels and zoomable on-screen vibration frequency plots with cursor readout. It can store lists (routes) of machines (up to 1000), each with up to 10 measurement points, all with full vibration waveform and frequency spectrum (FFT) capture.

Routes and readings can be transferred between the TPI 9080Ex and the packaged free, subscription free, PC based trending and reporting software in a variety of different ways.  Via the included USB docking cradle, wirelessly via Bluetooth or remotely via a Bluetooth link with a smart phone or tablet, running the free TPI Bridge App. This allows service personnel to receive and return routes and readings, no matter where they are in the world.  The PC software, includes automatic email notification of alarms and report generation, allowing you to implement a full CBM solution.

Clean energy technology set to decarbonise the world wins UK’s top award for engineering innovation

RAE 130723 114

 

 

 

 

 

 

 

 

Ceres Power’s pioneering clean energy technology has won the 2023 MacRobert Award. Honouring the UK’s top engineering innovations, the MacRobert Award was presented to Ceres in recognition of a ground-breaking fuel cell technology that promises to make a major contribution to decarbonising the world at the scale and pace required to save the planet. 

The Academy’s Royal Fellow, HRH The Princess Royal, presented the winning team behind the Ceres SteelCell with the MacRobert Award gold medal and a £50,000 prize at the Royal Academy of Engineering Awards Dinner in London on 13 July. 

Run by the Royal Academy of Engineering, the MacRobert Award is the UK’s longest running and most prestigious award for UK engineering innovation. Ceres joins an illustrious list of previous MacRobert Award winners, many of which have transformed the world we live in. From the CT scanner to the first television graphics system and the Raspberry Pi mini-computer, MacRobert Award winners have demonstrated the sheer capability of UK innovators to develop world-leading, commercially viable products across all sectors of engineering. The 2022 winner, Quanta Dialysis Technologies, has made portable, high-performance dialysis a reality.

To win the MacRobert Award, innovations must demonstrate outstanding engineering ingenuity, commercial success and tangible social benefit. Ceres’ pioneering clean energy technology includes fuel cells for power generation and electrolysers for green hydrogen. The judging panel was impressed with the solid oxide cell based on common low-cost materials, which is combined with an innovative deposition technique and a highly differentiated stack technology. This technology means that just one cell is enough to light a room but the 250 megawatts of capacity set to come on stream in 2024 could power half a million homes. 

Ceres has pioneered the use of commonly found materials: a gadolinium-doped ceria ceramic membrane as an electrolyte that operates at temperatures in the range of 500–600C. This is a ‘Goldilocks’ temperature for performance, fuel flexibility, cost and robustness. Ceres’ licensing model has enabled it to establish partnerships with companies such as Bosch, Doosan, and Weichai, to deliver systems and products at the scale and pace needed to decarbonise power generation, transportation, industry, and everyday living.

The judges were also impressed by the truly reversible technology. Running in one direction it can use multiple fuels to generate electricity highly efficiently when and where it is needed. Run in reverse, it generates green hydrogen at high efficiencies and low cost, an innovation the MacRobert Award judges praised as a huge breakthrough in the clean energy revolution. 

Professor Sir Richard Friend FREng FRS, Chair of the Royal Academy of Engineering MacRobert Award judging panel, said: “Engineering innovation is the driving force behind economic growth and a sustainable future.  It is impressive to see what Ceres Power has achieved with its SteelCell technology. The innovation promises to be a huge game changer for hydrogen generation and marks a significant breakthrough in clean energy technology, providing the tools for companies to reach net zero, even in the most hard-to-abate sectors.

“The engineering heroes behind the UK's world-changing engineering innovations deserve to be celebrated. Ceres’ spectacular work continues the UK’s proud tradition of world-leading engineering innovation and highlights the important contribution the UK can make in tackling the ongoing climate crisis.” 

Dr Caroline Hargrove CBE FREng, Chief Technology Officer at Ceres, said: “As a UK technology business, Ceres is playing an important role in decarbonising the global energy system, and we are thrilled to gain the recognition of the Royal Academy of Engineering as the winner of the 2023 MacRobert Award.  

“The UK is a science and technology powerhouse; as a nation we have invented some of the world’s best technology that we see all around us today. At Ceres, we believe the same can be true of hydrogen and fuel cell technology. 

“We have an incredibly talented team of nearly 500 scientists and engineers, pioneering electrochemical technologies that are enabling the world’s most progressive companies to deliver clean energy at scale and pace. And we need to succeed, to ensure that we can deliver a net zero future for our families, for society and for all our benefit.”

SDM Fuel Solutions named as one of UK’s fastest-growing private companies

SDM.jpeg

A fuel management specialist in the South has been named by The Sunday Times as one of Britain’s fastest-growing privately held companies at 14th place with annual sales growth of 174.98% over three years.

SDM Fuel Solutions, employing 45 people and led by Managing Director Simon Mayne, has seen annual sales exceed £6.1 million, with that figure on course to more than triple this financial year.

The company was founded by Simon, 37, and his late father in the family’s garden shed in the village of Binsted, near Ryde on the Isle of Wight.

With roots in the repair and maintenance of boats at marines, SDM Fuel Solutions expanded into tank cleaning after the son decided to see for himself what was involved in cleaning diesel tanks.

The company is currently based at Ower, just west of Southampton, and has plans to build a highly sustainable headquarters near Romsey on eight acres of disused land which would generate its own renewable power.

Simon said: “We’ve gone from starting out in a garden shed to a 20ft container to a warehouse and then offices for 75-plus people, with the exciting ambition for the new HQ, which would accommodate up to 200 people and includes a staff café, kitchen garden and a tree hide.

“I know my dad Simon, who passed away at 58, four years ago, would be incredibly proud of what has been achieved by his family and colleagues - The Sunday Times accolade will bring a wide smile on his face as he salutes us from above with a mug of tea.“

Simon’s father was well respected on the Isle of Wight – he owned SDM Marine Services, which managed the conversion of the Isle of Wight lighthouse from manned to unmanned.

He was joined by his son, who came from a background in superyachts, in 2009 and they initially focused on fuel treatment.

Then, in 2011, came the eureka moment; younger Simon saw a commercial future in tank cleaning, having seen first-hand how badly it had been done elsewhere.

Simon added: “Intrigued, I took a £300 course on tank cleaning and came back home on a Red Jet ferry across the Solent stinking of diesel.

“I said, ‘Dad, this is the way we should be going’, and our wives agreed – they were the ones who said we should really do this, they pushed us.

“As a result, SDM Fuel Solutions, incorporating my dad’s initials, was borne, with us growing tank cleaning and additive services in the marine sector. A massive fuel specification change in the industry also led to demand.

“We subsequently expanded into the tech sector, including FTSE 100 companies - data centres must have diesel generators as emergency back-up in case of outages because these are mission-critical business systems.

“The power generators need to run smoothly at a moment’s notice; there can be no room for contaminated fuel as this puts resilience at risk.“

As well as cleaning tanks that can hold up to 2 million litres, the company’s services include 24/7 emergency fuel, fuel polishing, fuel recovery, fuel sampling and site surveys, fuel uplifts and transfers, hydrotreated vegetable oil fuel, gas-to-liquid fuel, bespoke Jetstream filtration, fuel sampling kits, fuel testing, fuel cleaning and land decontamination.

Meeting The Sunday Times’ eligibility criteria, SDM Fuel Solutions has grown from a turnover of £250,000 to £6.2 million within four years due to significant commercial demand; a spin-out property division, which purchases and redevelops petrol stations, is expanding.

Simon put the success of the company down to ‘’great people and timing – we really have dialed in to employing great people, aligned with a long-term growth strategy underlined by our ‘inch-wide, mile-deep’ philosophy.

“The rate of growth is such that I’d be disappointed if we didn’t hit £30 million turnover by the last quarter of 2024. We are also looking at the water industry now as there is opportunity there.“

He also applauded the ‘pivotal work’ of three colleagues who particularly helped his father – Dean Scott, who held the fort while his dad was ill, Carl Shephard and Craig Chiverton.

SDM Fuel Solutions entered The Sunday Times listing following a suggestion from the company’s business coach, James Akin-Smith.

 

The Sunday Times citation reads: “The father-and-son team Simon and Simon Mayne dreamed of owning their own yachts rather than working on other people’s boats, so they set up SDM in 2011 to do just that. Based near Southampton, its main business is testing fuel for contamination and cleaning tanks. Mayne Sr died in 2019, leaving his son, 37, to achieve their dreams. Working with fellow directors Carl Shephard, 39, and Craig Chiverton, 38, Mayne Jr expects SDM’s sales to grow almost fivefold in two years, from £6.1 million last year to £30 million by 2024.”

CONTRINEX DNV-GL-APPROVED MARITIME INDUCTIVES HELP KEEP THINGS ‘SHIP-SHAPE’ VERIFYING THE SAFE CLOSURE OF DOORS

Like automation, Contrinex sensors are used in a wide variety of applications, and in this installation are trusted to ensure the safe and reliable control of weathertight doors on shipping.

 

 

1.jpeg

CUSTOMER APPLICATION

On ships, water-tight doors rely upon compressing seals around the perimeter of their frame, when they close. Double-acting hydraulic cylinders are used to open and close multiple linked latches that secure the doors when closed, maintaining their correct fit against the seals.

Designers required an affordable and highly reliable means of confirming the status of the latches, which would withstand the aggressive marine environment, being resistant to seawater, corrosion, vibrations and shock.

Contrinex has the advantage of offering a range of ‘Maritime’ inductive sensors which are approved to the DNVGL-CG-0339 environmental test specification for equipment to be installed on ships and offshore units. For example, the sensor’s EMC protection meets maritime requirements, particularly regarding power supply variations and low-frequency immunity, as well as being highly corrosion resistant, and IP68/IP69K rated.


DNV is an internationally accredited certification body that establishes and maintains technical standards for the construction and operation of ships and other offshore mobile structures in international waters. DNV is authorized by 130 maritime administrations to perform certification or verification on their behalf.

 

 

2.jpeg

CUSTOMER SOLUTION

A high-pressure rated inductive sensor was selected which is capable of operating in installations of up to 500 bar (7,255 psi) and at a peak pressure of 800 bar (11,603 psi). The sensors are embedded into the side of the double-acting hydraulic cylinders which drive the door’s power locking mechanisms. The sensors are located at either end of the cylinder to monitor the presence of the metallic cylinder tie rod, as it reaches the end of its travel, showing whether the door locks are fully open or fully closed.

A member of Contrinex’s uniquely robust ‘700 Series’ of inductive sensors, the sensor features a front face and cylindrical housing which is machined from a single piece of stainless steel. It’s thick front face provides extraordinary abrasion resistance and the sensor’s unique technology gives it unmatched abilities to resist shock and impact damage. This impact resistance is typically demonstrated by showing how a sensor survives being used to hammer nails into a wooden block.

In the Maritime range of sensors, V4A/ AISI 316L stainless steel is used to provide high corrosion resistance to seawater and a salt-laden atmosphere. The sensor’s location inside metal doors on the perimeter of ships also meant that their wide temperature operating range (-25°C to +70°C) and Contrinex’s industry-leading temperature stability and temperature-resistance is important for reliable service.

The sensor also contains the IO-Link communication protocol so that parameters can be auto-updated from the PLC to a new sensor when it is installed. IO-Link is also ideal for implementing the sensors into Industrial IoT (IIoT) and Industry 4 systems, for example for the continuous monitoring of sensor status.

 

3.jpeg

Combining exceptional durability in harsh environments with extended working life, Contrinex’s DNVGL-approved inductive sensors are an affordable, risk-free option for marine systems integrators and equipment designers.

PRODUCT ADVANTAGES

  • Operating pressure up to 500 Bar (7,255 psi), Peak 800 Bar (11,603 psi)
  • Uniquely robust 700 Series - One-piece stainless-steel (V4A /AISI 316L) housing and sensing face
