PolyGard® Carbon Monoxide CO Transmitter ADT-D3 1110 with Infrared Sensor DESCRIPTION CO transmitter with two-beam infrared sensor for the continuous monitoring of the ambient air to detect carbon monoxide concentrations. The infrared measuring method with integrated temperature and drift compensation stands for highest accuracy, selectivity and reliability despite of the calibration interval of 5 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. APPLICATION For the detection of carbon monoxide (CO) within a wide range of commercial applications such as underground garages, tunnels, engine repair shops, loading bys, engine test benches, shelters, go-kart race courses etc. Due to the standard analog signal and the RS-485 serial interface the CO transmitter is compatible to the PolyGard gas controller series by MSR-E as well as to any other controllers or automation systems.
