SENSITRON S2131CO CARBON MONOXIDE (CO) detector. 0-500 ppm. 4-20 mA

The SMART3G-C2 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 with a diameter of 48 mm. 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, the output has a 4-20 mA signal on three wires as standard. As optional, RS485 serial communication and a 1 or 3 relay card can be added. The case is made of aluminum with a total size of 120 x 184 x 90 mm, all inputs have 3/4" NPT threads
