A third-generation imported electrochemicalsensor is adopted. Depending on the sensortype, it can detect toxic and hazardous gasessuch as chlorine, ammonia, hydrogen chloride,hydrogen fluoride, propylene oxide, carbonmonoxide, phosphine, sulfur dioxide, vinylchloride, and formaldehyde. It features on-sitedisplay and an audible and visual alarm.
Operating voltage: 24 VDC or 220 VAC, three-wire system. It provides a standard 4-20 mAsignal output and can be connected to ourcompany's SA series alarm host, as well as PLCand DCS systems. It may also be poweredindependently for standalone operation, withon-site display of gas concentration and alarmfunctionality. The detection level is ppm (partsper million), with an accuracy of 0.1 ppm.
