C12-17 Combustible Gas Transmitters are three-wire transmitters, operating from 24 VDC power supplies and transmitting a 4-20 mA signal proportional to 0-100% LEL (Lower Explosive Limit) of a particular gas or vapor. It's available either as a blind transmitter or with an integral LCD display that provides local indication of gas concentration, visible through the glass window in the explosion-proof housing. Reliable Detection of Hazardous Concentrations of Combustible Gases The C12-17 Combustible Gas Detector is a stand-alone gas transmitter designed to detect potentially hazardous concentrations of combustible gases in ambient air. Gases and hydrocarbon vapors, such as methane, propane, butane, gasoline, toluene, hydrogen and many others, can be reliably monitored in process buildings, analyzer enclosures, pump stations, gas compressor stations or anywhere gases or vapors may build up to explosive levels. C12-17 Combustible Gas Detectors are three-wire transmitters available as either a blind transmitter or with an integral LCD display that provides local indication of gas concentration, visible through the glass window in the explosion-proof housing. Gas transmitter units supplied with the integral display also contain a single alarm set-point and relay for local alarm purposes. This integral relay is a latching alarm that can be reset with a magnetic tool without opening the enclosure. C12-17 gas transmitters can be connected directly to PLC, DCS, or computer-based alarm systems without additional hardware. Combustible gas sensors are made up of two matched sensing elements, one active and one passive.
