New A2L refrigerant gas sensor and pre-calibrated sensor modules

Figaro Engineering Inc., is pleased to introduce its TGS2630 refrigerant gas sensor and the new FCM2630 pre-calibrated gas sensor modules for A2L refrigerant leak detection.

The TGS2630 has high sensitivity to low-GWP A2Ls, "Lower Flammable Refrigerants", such as R-32 and R-1234yf. The TGS2630 is also sensitive to R-404a and R-410a which are commonly used in air conditioning and refrigeration systems. TGS2630 has a built-in filter to reduce the effect of alcohol and other interference gases, resulting in high selectivity to A2L refrigerants. This feature makes the sensor ideal for stationary type A2L refrigerant leak detectors which require long term durability and resistance against interference gases.

Using the TGS2630, FCM2630 is a small sensor module that is pre-calibrated for the detection of R-32. This module can be easily built into HVAC-R systems, eliminating the need for HVAC-R system manufacturers to calibrate as well as perform electronic circuit design for temperature compensation. In addition, a connector enables easy replacement of the gas sensor module for periodic maintenance.  FCM2630 is capable of attaining the performance requirements of the IEC60335-2-40 (Edition 6) and the JRA4068:2016 standard (Performance 3) established by the Japan Refrigeration and Air Conditioning Industry Association.
