The A12-17 Combustible Gas Detector is an advanced combustible gas transmitter that provides reliable measurement of combustible gas levels in industrial plant environments. Typical applications are ambient air monitoring near process tanks or piping, or in enclosed spaces where combustible gases may leak or accumulate.
The A12-17 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. As long as the active element remains in good condition, the gas sensor will respond rapidly to the presence of combustible gas.
