VQ22 Combustible Gas Detector Elements

Amphenol SGX Sensortech VQ22 Combustible Gas Detector Elements are improved poison-resistant sensor consisting of two matched elements which are used for the detection of combustible gases, particularly methane in air mixtures in concentrations from 0.1% upwards. The VQ22 Series has no interference from water vapour or carbon dioxide. Using the recommended bridge circuit below and the suggested mounting arrangement, the minimum sensitivity is 10mV/% methane. The VQ22 has been designed for use in atmospheres where traces of silicone and other poisoning agents may be present.
