Gas sensor leakage detector CO2 infrared version out: 0-5V, 1-5V, 0 to 10V, 2 to 10V, 4-20mA, RS485 Modbus

The refrigerant gas leak sensor is a device that signals leakages of common gases (R22, R134a, R404a, R407c, R410a, R290, NH3, Ethylene and CO2). 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 identifi cation of gas leaks, avoiding having to shut the unit down and at the same time guaranteeing the safety of any people in the vicinity. Each model is calibrated for a specifi c gas and is typically installed in new or existing buildings that require continuous monitoring of gas leaks. Available in semiconductor or infrared version with enclosure IP41 and IP66 versions, built-in and with remote sensor.
