ABSTRACT:
A gas flow type angular velocity sensor which is capable of reliably sensing an angular velocity while accurately controlling the working gas flow with temperature compensation by using a pair of heat wires as a gas flow sensor without providing any additional gas flow sensor in the sensor body wherein an angular velocity sensing bridge circuit is provided at its current supply source with a temperature compensating circuit connected in series which temperature compensating circuit is composed of a pair of series or parallel connected resistance elements, one of which is a thermosensitive resistance element disposed in a gas path and the other of which is a reference resistance element disposed outside the gas path.
