Intelligent gas detection transmitter
International Sensor Technology has just introduced its Model 4-201Q, an intelligent sensor transmitter that can be equipped with solid-state, electrochemical or catalytic bead sensors for detection of over 150 hazardous gases, including hydrogen, sulfide, ammonia, carbon monoxide and combustibles. The microprocessor-based unit operates on 14-24 Vdc and provides a linear 4-20 mA analog output. Housed in an explosion-proof enclosure which is CSA and UL classified, it features a local digital display of gas concentration, automated calibration and a magnetic wand operation that allows non-intrusive calibration, eliminating the need to declassify hazardous areas.
