The Importance of Calibrating Fixed Gas Detectors for Safety

Fixed gas detectors play a critical role in safeguarding people, places, and the planet against potentially life-threatening gases in environments ranging from high value industrial complexes to laboratories and hazardous confined spaces. However, to ensure their accuracy and reliability, regular calibration is an indispensable practice.

 

Calibration is usually a two-step procedure – the zero and the span. In the first step, the sensor is zeroed using ambient air after confirming that the target gas is not present or by using a suitable gas from a cylinder. The second step is to expose the instrument to the calibration gas that contains a known concentration of the target gas the sensor is designed to measure. The readings are then adjusted to match these values.

 

Whether an instrument warns and/or alarms at the proper time depends on its ability to translate the detected concentration of a target gas into an accurate reading

 

During calibration, gas detectors perform relative measurements. Rather than independently assessing the quantity of gas present, they measure the concentration of targeted gas within a test gas mixture by comparing real-time sensor response to the sensor’s response to a known concentration of target gas that the instrument is configured to detect and measure. This “known concentration” test gas serves as the instrument’s measurement scale, or reference point.

 

So, why is this important? Here are a few reasons to consider:

 

1. Ensuring Gas Measurement Accuracy and Reliability

A gas detector that isn’t accurately calibrated can lead to mis-readings, false alarms, and inadequate responses to hazardous situations. Proper calibration fine-tunes the detector’s sensor(s) to maximise speed of response, measurement accuracy, and provide reliable information to personnel required to make informed decisions in critical moments.

 

2. Meeting Regulatory Compliance

Safety regulations and standards are in place for a reason – to protect people, property, and the environment from potential hazards. Many industries are subject to these regulations that dictate the calibration and maintenance of gas detectors.

 

3. Mitigating False Alarms and Detection Failures

A poorly calibrated gas detector can lead to unnecessary evacuations, disruptions, and complacency due to frequent false alarms. Conversely, improper calibration might render a detector insensitive to dangerous gas levels, leaving people and operations vulnerable to potential harm.

 

4. Accounting for Changing Environmental Conditions

Fluctuations in temperature, humidity, and atmospheric pressure can impact the performance of these instruments. Regular calibration adjusts for these variables, ensuring that the sensor maintains its accuracy despite ever-changing conditions.

 

5. Combating Sensor Drift and Aging

Just like any mechanical or electronic component, gas sensors can experience signal drift or degradation over time. When the detector’s current readings deviate from the known reference, proper calibration procedures enable necessary adjustments to the sensor’s output. This adjustment effectively brings the sensor’s response back in line with the original calibration reference, minimising the impact of sensor drift.

 

6. Upholding Record Keeping and Liability

In the age of accountability, maintaining thorough records of gas detector calibration is a prudent practice. It demonstrates a commitment to safety management and can serve as a valuable resource in case of incidents or accidents. Having well-documented calibration records can potentially mitigate legal liabilities and bolster an organisation’s credibility.

 

7. Fostering Confidence in Safety Systems

An accurately calibrated gas detector is not just a piece of equipment; it’s a testament to an organisation’s dedication to safety. Regular calibration instils confidence in employees and management that the safety systems are in optimal condition, ready to provide accurate information and timely alerts in case of emergencies.

 

Conclusion

Routine calibration helps ensure accurate measurements, regulatory compliance, and a reliable defence against hazardous gases. Onsite safety and instrument availability is maximised while mitigating against false alarms at the same time. In a world where safety is paramount, the simple act of calibration speaks volumes about an organisation’s commitment to the well-being of its people and the environment.

ESI are celebrating 30 years of the SOS sensor this year!

esi.jpeg

Silicon-on-Sapphire (SOS) sensor technology has emerged as a cornerstone in the design and functionality of ESI's intrinsically safe pressure transmitters, playing a pivotal role in ensuring reliable and accurate measurements in hazardous environments. The combination of silicon's sensing capabilities and sapphire's resilience creates a symbiotic relationship that addresses the challenges posed by harsh environments in hazardous locations.

The SOS sensor leverages the exceptional properties of both silicon and sapphire to deliver unparalleled performance. The Sapphire offers remarkable durability, chemical inertness, and resistance to extreme temperatures. The silicon is grown onto the surface of the sapphire substrate creating a sensor that benefits from the best of both materials. The silicon provides sensitivity and accuracy, while the sapphire substrate shields it from corrosive chemicals, abrasive substances, and high temperatures, ensuring long-term reliability in even the harshest environments.

The use of Silicon-on-Sapphire Technology is particularly crucial in intrinsically safe pressure transmitters designed for hazardous locations. In environments where the risk of explosion is present, safety is of utmost importance. Intrinsically safe devices are engineered to prevent the release of sufficient electrical or thermal energy to ignite a hazardous atmosphere. ESI's pressure transmitters, incorporating SOS sensor technology, meet these stringent safety requirements while delivering accurate and dependable pressure measurements.

The inherent electrical insulation properties of sapphire play a pivotal role in achieving intrinsic safety. Sapphire is an excellent insulator, preventing the passage of electric current and reducing the risk of sparking or overheating. This makes SOS sensors inherently safer for use in explosive atmospheres compared to traditional sensors that may pose a higher risk.

Additionally, silicon-on-sapphire technology enables ESI to create pressure transmitters with a compact design without compromising performance. The thin, yet robust, nature of the SOS sensor allows for the development of smaller and lighter devices, making them easier to install and maintain in tight spaces within industrial facilities.

As industries continue to prioritise safety and accuracy in their operations, SOS technology is poised to remain at the forefront of intrinsically safe pressure transmitter solutions, providing a reliable and durable solution for critical applications.

CLIMATE CHALLENGE:

hart_doors_1.jpeg

“Whatever the weather, business must go on” say Hart

With a significant number of major storms hitting the UK, Climate Change inevitably raises its threatening head yet again writes Nick Hart, managing director, Hart Door Systems.

As an island the UK’s climate has always been influenced by its surrounding seas and the near Continent, be it Scandinavia or Europe. There are however subtle changes afoot as demonstrated by the 10 named storms between September 2023 and the end of January 2024 which most recently included warnings of isolated Tornados hitting us.

Under this process of change what does this mean for industry? We at Hart Door Systems lead the way in taking on the storm threat through our high-speed Speedor range of highspeed doors in particular with our Speedor Storm which has been specifically designed to face the storm challenge.

The automated Speedor Storm has wind resistance on a large external openings in mind, up to 6m x 8m or 8m x 6m. Available up to class 5 as defined by DIN EN 12424, the best maximum test pressure capable of withstanding 1250 Pa of pressure across the door face, the equivalent of wind in excess of 70 miles per hour.

The smaller the door the higher the wind speed it can withstand as all Speedor Storms have the same construction. If a client wants a door capable of even higher wind-loads than wind-class 5 then we offer the Typhoon door which can meet either a 3000Pa specification or a 4000Pa and can be made up to eight meters wide. This product is ideal for very high wind-load situations and is why it’s been so successful in the Far East where they regularly experience tropical Cyclones.

Most recently Hart despatched an SR4 roller shutter for Indonesia. It is presently at sea around South Africa due to Red Sea security issues. When it arrives this very high security shutter with rapid door operation will be installed by the client with technical video support from Hart’s headquarters at key stages of the installation process. 

Returning to the issue of climate, clearly there is a need for industry to pay attention to accelerating storm threats because manufacturing and subsequent product distribution generates frequent use of industrial doors. If not automated, doors can be left open disrupting the working environment and wasting expensively heated air. Whatever the weather, business must go on.

Zero ozone depleting potential with Tundra refrigerant air dryers

As of 2024, the entire popular and high-performing Tundra range of refrigerant air dryers from Hi-line Industries will transition to R-513A, a refrigerant with zero ozone depleting potential (ODP) that helps customers to enhance their sustainability credentials. Although Hi-line attributes the success of the Tundra range in compressed air applications to its ultra-reliable performance, energy efficiency and reasonable price tag, the introduction of R513-A and its zero ODP means there really is no need to go anywhere else for refrigerant air dryers.

R-513A (Opteon™ XP10) refrigerant is a hydrofluoroolefin (HFO) based replacement for R-134a. Ideal for use in medium and low temperature refrigeration products, such as Tundra air dryers, R-513A offers 56% lower GWP (global warming potential) than R-134a, delivering long-term sustainability and F gas legislation compliance.

Notably, R-513A resides in the A1 (non-flammable) safety class, making it an ideal retrofit candidate for R-134a, while offering very similar cooling performance. R-513A also provides negligible temperature glide to ensure reliable performance day after day.

Despite the new innovation in refrigerant development, Hi-line intends to hold pricing for the Tundra range firm throughout 2024. This initiative will help customers combat challenging trading conditions and remain competitive in their respective industries.

                                                                                                                                                                        

Tundra refrigeration air dryers are in widespread use across UK industry, improving the quality of compressed air, protecting valuable assets, and outperforming rival technologies in energy efficiency by minimising pressure drop and lowering absorbed power. Among further features driving Tundra’s energy-efficient characteristics is a patented single-cell heat exchanger, which delivers highly efficient heat transfer at low energy costs, and a link between the controller and condensate removal valve for minimum loss of compressed air during condensate discharge. To indicate the regard held for Tundra as a value-added solution for companies running compressed air systems, this innovative product recently gained recognition at the prestigious iPlex Awards, in the ‘Energy Management Innovation’ category.

Indeed, the acknowledgement of Hi-line’s impact on industry stretches far beyond Tundra refrigeration air dryers, with Managing Director Steve Smith’s recent induction into the Industrial Plant and Equipment Hall of Fame a case in point. Steve Smith has a depth of experience in the compressed air sector that spans over 40 years. In particular, the judges praised his commitment to corporate social responsibility, whether it is his willingness to take the lead on charity initiatives, or Hi-line’s sponsorship of local sporting teams. On this note, the company will continue to sponsor Tom Hamer, defender at League One football club Burton Albion, throughout the 2023/24 season.

Hi-line are also sponsors of Burton Rugby Football Club – First Team with the logo on the chest of all the First Team Shirts. Along with the sponsorship of the Hi-line Moto X team, this year Hi-line’s sponsorship is extend further by sponsoring Help for Heroes to enable the rehabilitation of war veterans to travel pillion on a motor cycle along Route 66.

ATEX, UKCA and IECEX Equipment Manufacturers Quality Requirements

Given the onerous nature of an explosion, special certification schemes have been set up to control the design and certification of equipment for use in potentially explosive atmospheres.  Although the schemes differ globally (some are mandatory under law, some are simply procurement specifications), the bases for design and certification is similar, and the schemes normally rely on empirical testing, constructional assessment and ‘production control’ by a recognised Certification Body.

The production control (quality management) part of certification is known as a Quality Assurance Notification (ATEX and UKCA) or Quality Assurance Registration (IECEx) and the Standard that is applied is EN ISO IEC 80079-34. The Quality Module/Registration permits the manufacture of equipment that holds a ‘Type Examination’ Certificate where the concept of the certification (for example Flameproof, Ex d) is covered by the quality assessment and certificate. The Quality Module/Registration is considered an ‘Add on’ to ISO9001. It requires ATEX to be addressed or considered in each applicable clause of the Standard of ISO9001 or that a ‘Quality Plan’ be created that also adequately addresses the requirements.

Quality Module/Registration audits are normally conducted by an auditor with experience of both Quality Systems and Hazardous Area products. Unlike an ISO audit, where the worst-case scenario is losing your ISO accreditation, non-compliances in a Quality Module/Registration could lead to your products being recalled from the market!

These requirements require an internal person (normally referred  to as the ‘Authorized Person’ to have significant knowledge of EN ISO IEC 80079-34 and the protection concepts used for manufacturing. An example of the types of things the Ex Quality System would need to address are given below:

  • On receipt of an EX sales enquiry, how do you ensure that what the customer requests is covered by your certificate? (gas groups, zone, temperature class, etc.)
  • How would you indicate and control an EX build from the design plan?
  • Controls in place to ensure  all units are built to within the scope of the ‘schedule’ drawings (the drawings listed on the certificate).  Ensure these drawings remain unchanged, if a change is required apply for a ‘variation’ through the issuing Body.
  • How would procurement be controlled to ensure suitably rated EX parts and/or materials are sourced and verified ?
  • Are EX parts inspected prior to installing them by someone with appropriate competence ?
  • How do you know what other special features are required for an EX build
  • Is everyone who works on an EX unit specially trained on Ex equipment Installation and Inspection.
  • Were all materials such as potting/encapsulation within ‘use by’ dates?
  • Does the final inspection and test plan cover the EX routine tests and requirements?
  • Record all routine tests with signatures/tractability. Ensure all equipment is calibrated.
  • Ensure you have a record of where each ATEX certified unit is delivered in case there needs to be a re-call.
  • Cover ATEX on agendas for management meetings (to discuss related issues) and in your audit schedule.
  • Considered Standards listed on your CE/UKCA Declaration of Conformity within your Quality System as controlled documents. You should have a mechanism for knowing when these standards change or are withdrawn and take the appropriate action.
  • Have an ‘EX Authorized Person’ listed in your ATEX Quality Module System, this person is normally technical and well trained in ATEX, and  is the ‘go to’ person for interpreting the schedule drawings, working with the Notified Body and periodically reviewing the Standards.

 

ExVeritas issue ATEX and UKCA QANs, IECEx QARS, UKAS ISO9001 and other global quality approvals such as INMETO and CCC audits. ExVeritas also offer ‘Ex Authorized Person’ training for both internal and external auditors. Please view our training for more details. www.exveritas.com

Why do we need intrinsically safe instrumentation?

Typical hazardous locations include the more obvious places such as flour mills, coal mines, petrochemical plants, fuel transfer facilities etc. However, some not so obvious hazardous locations also include waste water treatment plants, saw mills, tunnels and underground passageways or any location where a build-up of naturally occurring flammable material (such as methane or dust) could occur.

In many of these locations there is a need for condition monitoring, i.e. measuring the vibration levels and temperature of rotating machinery. The equipment needed to do the monitoring must therefore be “intrinsically safe”, in other words it must be incapable of igniting an explosive atmosphere, should one exist.

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require employers to control the risks to safety from fire and explosions. Consequently, 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.

The likelihood of an explosive atmosphere existing is dealt with in these standards by the definition of various zones. However, it is the responsibility of the plant operator to decide which parts of their plant are in which zones.

For IECEx (Worldwide) & ATEX (European) standards the following zones are defined:

Zone 0 - an area in which an explosive atmosphere is present constantly or for long periods or frequently.

 

Zone 1 - an area in which an explosive atmosphere is likely to occur in normal operation occasionally.

 

Zone 2 - an area in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

Intrinsically safe instruments can cost many times more than their non-intrinsically safe equivalents. This is partly due to the increased manufacturing costs (e.g. additional safety components and encapsulation) but also due to the high cost of certification. However, Test Products International (TPI) believes it has achieved a real breakthrough with the very affordable TPI 9080Ex vibration analyser. The TPI 9080Ex combines on-meter diagnostics with the all-important ability to TREND readings over time to simplify condition based maintenance (CBM).

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 uses industry standard BNC connected intrinsically safe accelerometers and offers on-meter analysis for the detection of machine faults such as unbalance, misalignment, looseness and bearing wear. With full colour OLED display and Bluetooth communications, the TPI 9080Ex features colour coded alarms and zoomable on-screen vibration frequency plots with cursor readout. It can store lists (routes) of up to 1000 machines, each with up to 10 measurement points, with full waveform and frequency spectrum (FFT) capture.

The included free-to-use VibTrend PC-based trending and reporting software features high-end benefits such as automatic email notification of alarms and report generation to implement a full CBM strategy.  Routes and readings can easily be transferred to/from the TPI 9080Ex via Bluetooth using a smart phone or tablet running the free TPI Cloud Bridge App. This allows service personnel to be sent routes and return readings, no matter where they are in the world. 

In-line with TPI’s philosophy of being the value leader, the TPI 9080Ex has a list price of only £3,500.
