Description
New MPS™ Refrigerant Gas Sensor provide accurate and reliable detection of mildly flammable (A2L) R-32, R-454b blends, R-1234yf and other low global warming refrigerant gases such as (A1) R744 as well as (A3) R290 and R600 common in HVAC-R applications. With a 15+ year calibration interval and lifetime, the MPS™ A2L Refrigerant Sensors deliver industry-leading performance and the lowest total cost of ownership.
Operating Principle
The Molecular Property Spectrometer™ (MPS™) A2L Refrigerant Sensors 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. The 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.
