ABSTRACT:
A catalytic gas detector circuit in which a resistive gas detector element is common to two bridge circuits, and wherein the resistance and temperature of the detector element are maintained essentially constant. This permits the use of a dynamic compensator element without encountering hysteresis effects and improves the response time of the circuit.
