SENSITRON S3231AM AMMONIA (NH3) detector. 0-5000 ppm. 4-20 mA

The SMART3G-D2 detector is suitable for installation in industrial areas and ATEX zones; thanks to the explosion-proof case it can be installed in zone 1 and, if equipped with the dust adapter, in zone 21. The sensitive element is housed in the stainless steel head. For the reading of toxic gases, the electrochemical cell is used as a sensor, which is well suited for the detection of substances at low concentrations. The detector has a 12-24 Vdc power supply, an output signal of 4-20 mA and three relays. RS485 serial communication can be added as an option. The case is made of aluminum with a total size of 145 x 187 x 108 mm. All inlets are threaded with 3/4” NPT thread. The SMART3G-D2 features a 7-segment display to view real-time concentration and Hall effect sensors for non-intrusive field calibration
