NevadaNano’s Molecular Property Spectrometer™ (MPS™) A2L Refrigerant Gas Sensor provides accurate and reliable detection of mildly flammable (A2L) R-32, R-454b blends, R-1234yf and other low global warming refrigerant gases common in HVAC applications. With a 1O+ year calibration interval and lifetime, the MPS A2L Refrigerant Gas Sensor delivers industry-leading performance and the lowest total cost of ownership.

Operating Principle

The Molecular Property Spectrometer (MPS) A2L Refrigerant Gas Sensor’s transducer is a micro-machined membrane with an embedded Joule heater and resistance thermometer. The MEMS transducer is mounted onto a PCB and open to ambient air. Presence of a flammable refrigerant gas causes changes in the thermodynamic properties of the air/gas mixture that are measured by the transducer. Sensor data are processed by patent-pending algorithms to report an accurate concentration.
