A complete line of industrial-quality gas sensors and monitors for refrigerants and other common gases is available. They utilize a range of sensing technologies including electrochemical, semiconductor, and infrared sensors to selectively detect most gases. The sensors are suitable for use in industrial refrigeration engine rooms, cold storage rooms, processing rooms, truck docks, and for relief valve vent lines. They are also suitable for use in supermarkets, and large institutional and commercial buildings. Typical gas detection applications include ammonia, carbon dioxide, hydrocarbons, HFCs, and CFCs. The analog outputs (4-20mA or 0-10vdc) can interface with nearly any existing monitor, computer, or PLC controller. The sensors have built-in visual and audible alarms. An auxiliary 1-A relay output is standard. A range of enclosures are offered to suit most applications.
