C12-17 Combustible Gas Transmitter USED

C12-17 Combustible Gas Transmitter is a stand-alone gas sensor to detect hazardous levels of combustible gases in ambient air.  This USED unit comes with your choice of range (new sensor), without a display, and in an XP Rated Enclosure.

The Model C12-17 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, and gas compressor stations. In fact, anywhere gases or vapors may build up to explosive levels can be readily monitored using this transmitter.
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. The gas transmitter is a USED unit but comes with a new sensor, comes without a display but in an XP Explosion Proff Enclosure.

Sensor Operation:

 Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit. When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas heating the active element and changing its resistance. The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration.
This C12-17 Combustible Gas Transmitter has explosion-proof sensor assemblies that are made of 316 stainless steel for maximum corrosion protection. A sinter bonded flame arrestor provides the gas diffusion path to the sensing elements while maintaining the flame-proof integrity of the assembly. Sensing elements are specially designed for maximum poison resistance and long life in harsh industrial environments, with sensor life typically 2 years or more.
