Mga SGD4x A2L Sensor ng Refrigerant

Sensirion SGD4x A2L Refrigerant Sensors are Refrigerant Detection Systems (RDS) designed for HVACR applications. The Sensirion SGD4x sensors operate on the thermal conductivity principle and include a dual dry-contact relay output to trigger a blower, shut off the load, or alert a control board. An LED status indicator provides quick visual feedback for easy installation. With fast response times and multi-refrigerant calibration, the devices support A2L refrigerants, making them ideal for residential and commercial systems.
