ADTD3 20XX Refrigerant Gas Twin Beam Infrared Sensor

Refrigerant gas transmitter with two-beam infrared sensor for the continuous monitoring of the ambient air to detect hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerants. The infrared measuring method with integrated temperature and drift compensation stands for highest accuracy, selectivity and reliability despite of the calibration interval of 3 years. The ADT-D3 possesses a standard analog output (0) 4- 20 mA or (0) 2– 10 V DC, and an RS-485 interface. 2 relays with adjustable switching thresholds as well as an integrated display are available as options.

For leak detection in cooling systems with refrigerant gases (HCFC and HFC) as cooling agents, and also within a wide range of commercial and industrial applications. Due to the standard analog output signal and the RS-485 serial interface the refrigerant.
