Cubic R32 A2L Refrigerant Sensor

The AM4205H-LC-R32 NDIR A2L refrigerant gas sensor by Cubic detects R32 gas for safety or alarms. Using industry standard UART, in seconds the sensor begins reporting 0-50% LFL (Lower Flammability Limit, equal to LEL Lower Explosive Limit) in with high accuracy. Analog voltage output is also available. R32 (difluoromethane) and R32-based refrigerant blends have been identified as the lead alternative refrigerant in the HVAC/R market. However, because R32-based refrigerant gases are mildly flammable per ISO 817:2014, they have an A2L classification that requires HVAC/R systems to incorporate a gas leak detection and mitigation system according to UL 60335-2-40 Edition 3 Annex GG & LL. Features Non-dispersive infrared (NDIR) technology Industry-standard serial UART or analog voltage outputs Reference channel for self-compensation and long-term stability No calibration required Built-in temperature and humility compensation Built-in heater for low-temperature operation to -30C Fast r
