NET REMORA MODULES

The Remora module is the newest addition to our NDIR range. This very cost effective device has the same features and gas list as the IREF-Lite but it is designed to be integrated directly on chillers and other refrigeration equipment instead of a gas detector. Every aspect of the hardware can be fully tailored on the customer’s criteria and application needs. KEY...

NEW ATEX MARKING FOR NET2X/3X – NOW FOR USE IN UNDERGROUND MINES

NEW ATEX MARKING FOR NET2X/3X SENSOR HEADS – NOW FOR USE IN UNDERGOUND MINES NET has just renewed the ATEX certificate for NET2X/3X sensor heads (certificate CESI01ATEX066U). In addition to the existing “II 2G Ex db IIC Gb” marking, from May 2022 the enclosures will be available also with the "I M2 Ex db I Mb" marking. This significant addition allows...

IS YOUR SENSOR FAIL-SAFE?

According to Wikipedia, fail-safe in engineering is “a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause no or minimal harm to other equipment, the environment or to people”. In other words, a fail-safe system is designed to avoid situations where a fault which prevents the...

What is SIL

According to Wikipedia, “Safety integrity level (SIL) is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a safety instrumented function (SIF).” With certification requirements for industrial fire and gas detection (especially in Europe with the introduction of...

Refrigerant leak detection: IR vs SEMICONDUCTOR SENSORS

When it comes to refrigerant leak detection, the predominant sensing technologies are undoubtedly Non-Dispersive InfraRed (NDIR) and Metal-Oxide Semiconductor (MOS), due to their ability to respond to this type of target gases and the many limitations of other common detecting methods such as electrochemical cells and catalytic pellistors. NDIR and MOS technologies differ both in functioning and in price...

IR SENSORS ARE LIKELY TO BE THE MOST PRACTICAL LEAK DETECTION OPTION WITHIN THE COMMERCIAL/INDUSTRIAL HVACR SECTOR, ACCORDING TO AHRTI REPORT No. 9009 – LEAK DETECTION OF A2L REFRIGERANTS IN HVACR EQUIPMENT

During the course of 2017, the Air-Conditioning, Heating and Refrigeration Technology Institute, Inc. (AHRTI) released a complete assessment to investigate which of the available refrigerant sensor technologies would be able to meet the anticipated update of current international and U.S. standards for HVACR systems. Specification requirements for A2L refrigerants, including refrigerant sensor requirements such as response time and measurement ranges,...
