A2L Refrigerant Leak Detection Sensors
Despite being environmentally friendly and energy-efficient, A2L refrigerants are mildly flammable, making them a potential risk if not managed effectively. The early detection of A2L refrigerant leaks prevents the escalation of potential fire hazards, protects against possible health risks, and saves valuable energy by ensuring HVAC/R systems function at their highest efficiency.
At Sensors Converge, we’ll be showcasing MEMS A2L refrigerant leak detectors that utilize proven thermal conductivity technology. Since refrigerants and air have very different thermal conductivity, a variation in the refrigerant concentration results in significant changes in the thermal conductivity of the gas mixture, which Posifa Technologies’ sensor uses to detect a refrigerant leak. Its precision in detection can achieve a threshold as low as 20 ppm to ensure the safety and efficiency of HVAC/R systems.

Hydrogen Sensors
At Sensors Converge, we’ll be demonstrating hydrogen sensor solutions for applications such as leak detection, process control, and safety systems. Our solutions are based on a MEMS sensor that measures the change in thermal conductivity of the air when hydrogen is present, such as is fuel cell systems, battery management system (BMS) compartments, and hydrogen electrolyzer processes. In all of these, Posifa Technologies makes hydrogen detection more affordable, reliable, and space-efficient with sensors built on our highly repeatable, high-volume CMOS MEMS technology.

Vacuum Gauges
We’ll also be showcasing MEMS Pirani gauges for atmosphere (ATM) to medium vacuum applications that are the most economical, high-performance devices on the market. They offer excellent accuracy, wide ranges, longevity, and long-term stability, while minimizing the total cost of ownership by eliminating the need to calibrate replacement probes.
Our vacuum gauges each feature an individually calibrated probe that incorporates the sensing element and digital electronics. The devices output voltages can be customized to emulate those from other manufacturers’ gauges, enabling plug-and-play replacement for enhanced performance and reduced total cost of ownership, without any need to change system software or connection hardware.
