MD61 Thermal Conductor Gas Sensor

Profile
MD61 gas sensor consists of an active element and a reference element with the same resistance, both elements are placed in a Wheatstone bridge circuit. Along with the analyzing gas contents change, the overall thermal coefficient of mixed gases changes correspondingly. When the active element meet the combustible gas, its resistance become smaller, and when It meet reducing gas, its resistance become larger(air background). Then the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The reference element performs as a benchmark while for temperature compensation.
