Infrared Gas Sensors for Enhanced Refrigerant Safety and Compliance

Process Sensing Technologies (PST), a leading global provider of measurement and monitoring systems for critical process applications, is pleased to announce the successful attainment of UL60355-2-40 certification for the Axiom A2L refrigerant detector.

Engineered and manufactured by Dynament, a PST subsidiary and renowned pioneer in gas sensing technology, the Axiom A2L detector is poised to transform the detection of A2L gases like R32 and R454 blends. This certification represents a significant milestone in supporting new regulations aimed at mitigating the environmental impact of inadvertent refrigerant leakages and emissions from air conditioning systems and heat pumps.

The Axiom A2L detector employs cutting-edge nondispersive infrared (NDIR) technology, providing unmatched capabilities to facilitate OEM integration efforts in meeting regulatory mandates. Key features of the Axiom detector include:

• Rapid Response: Detects leaks in under 10 seconds.

• Versatile Output Options: Analog (voltage, milliamp, open collector) and digital (Modbus) output choices enhance flexibility.

• Wide Input Voltage Range: Operates within a voltage range of 5 to 24 volts DC power input.

• Onboard Heater: Fitted with a built-in heater to prevent condensation-related issues, ensuring reliable performance in diverse environmental conditions.

• Longevity: Offers a 15-year lifespan with no need for field calibrations, delivering cost-effective and trouble-free operation.

• Reliability: Fail-safe operation and resistance to poisoning ensure consistent performance over time.

• Compact Design: With dimensions of 1 x 2 x 3 inches and integrated mounting tabs, the detector can be conveniently positioned to support leak detection.

• Diagnostic Support: PC diagnostic tool facilitates service and maintenance assistance.

Kevin McKeigue, VP of the PST Sensor Division, expressed his thoughts on this significant achievement, stating, “Dynament has been a leader in NDIR sensing technologies for over two decades, and their expertise aligns well with this critical environmental initiative. The Axiom represents a substantial advancement in gas measurement innovations for the HVAC industry, providing a comprehensive and seamless solution to meet evolving industry standards.”
