Gas Sensor leakage

GLD Series


The refrigerant gas leak sensor is a device that signals leakages of common gases. It can be used in stand-alone applications, or integrated into CAREL controllers or third party devices. Connection to CAREL controllers is made using an analogue or digital output or Modbus® RS485 serial connection. When leaks are detected exceeding a certain concentration, the sensor sends an alarm signal to the controller, activating a local audible and visual warning and a relay (SPDT). This allows prompt identification of gas leaks, avoiding having to shut the unit down and at the same protecting any people in the vicinity. Available in versions with a semiconductor or infrared detector.
