The Model SM95 SENSOR transmitter is housed in an explosion-proof The Model 4-20 IQ is a microprocessor based intelligent SENSOR trans- casing and operates on 14-24 VDC power. It provides a 4-20 mA mitter. It comes equipped with a digital display which provides a local output proportional to the gas concentration and is calibrated by adjusting reading of the gas concentration. Operating on 14-24 VDC power, it potentiometers located inside the housing. The SM95 can operate as a provides a linear 4-20 mA output proportional to the gas concentration stand-alone instrument or can be used in conjunction with any of IST s and, like the SM95 and SM84 transmitters, it is housed in an explo- complete line of control units which provide control room sion-proof casing.
