Combustible gas detector and method for its operation |
摘要 |
A catalytic bead sensor or a semiconductor sensor is operated in a manner in which the power requirement is greatly reduced. The reduction in power is accomplished by operating the sensor at a temperature less than the desired operating temperature in the absence of a combustible gas and increasing to the desired operating temperature when the sensor is exposed to a combustible gas.
