Refrigerants keep things cool, but many newer refrigerants are also mildly flammable and can ignite if they leak. That’s the last thing you need from a refrigerant, so keep a digital eye out for leaks with Amphenol T3400 Series A2L Refrigerant Leak Detection Sensors.
These sensors utilize second generation MEMS technology to measure the thermal conductivity of the surrounding air, capable of targeting R454B and R32 refrigerants, and can offer accuracy of up to 2.5% in 30% to 70% Relative Humidity (RH). Their fast response of less than 15 seconds along with their long lifespan of more than 15 years makes these sensors indispensable in long-term, critical refrigerant applications, and their 3.3V to 5V and 22mA supply makes them compatible with most microcontrollers. Finally, they operate from -40°C to +60°C and pressures from 70kPa to 120kPa for application versatility.
