Combustible gas gas sensor MD62

CO2thermal conductivitymonitoring

MD62 gas sensor consists of an active element and a reference element with the same resistance, both elements are placed in a wheatstone bridge circuit, The analyzing gas contents changes, the overall thermal coefficient of mixed gases changed correspondingly; when the active element meet the combustible gas, its resistance become smaller, when It meet other gas, , Its resistance become larger(air background), the bridge circuit output the voltage change, this change increase according to gas concentration, the reference element as a benchmark while for temperature compensation. Application Industrial spot for CO2 detecting. Features Linear output signal Good reproducibility and reliable performance Resistant to toxicosis Detecting without Oxygen or short of oxygen
