发明名称 Combustible gas detector having catalytic sensor stabilizing network
摘要 A catalytic gas detector circuit in which the temperature of a resistance gas sensing element, contained in a bridge circuit, is temporarily increased by energizing a current changing network for a finite period of time sufficiently long enough to burn impurities off of the surface of the sensing element.
