SO2 transmitter including digital measurement value processing and temperature compensation for the continuous monitoring of the ozone concentration in the ambient air. A comfortable calibration routine with selective access release is integrated in the transmitter. The ADT-53 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 are available as an option.
For the detection of sulphur dioxide within a wide range of industrial and commercial applications. Due to the standard analog signal and the RS-485 interface the SO2 transmitter is compatible to the PolyGard series MGC and DGC by MSR-E as well as to any other electronic control or automation system.
