At Sensors Converge, we’ll be demonstrating solutions for detecting thermal runaway in battery management systems (BMS) and refrigerant leaks in HVAC systems. The solutions are based on a MEMS hydrogen sensor, which detects hydrogen concentration in the air by measuring the change in thermal conductivity of the gas mixture inside BMS and HVAC compartments.
Hydrogen detection is the state of the art for triggering battery failure alarms in electric vehicles (EVs) since hydrogen sensors react faster than pressure sensors to short circuit conditions and battery cell overcharge. It is also key for active leak detection of new low global warming potential A2L refrigerants — which contain hydrogen atoms and are flammable — to meet safety standards in HVAC systems. For both applications, Posifa Technologies makes detection more affordable, reliable, and space-efficient with sensors built on our highly repeatable, high-volume CMOS MEMS technology.
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.
