RESISTIVE GAS TRANSDUCER Russian patent published in 1997 - IPC

FIELD: determination of concentration of gas. SUBSTANCE: resistive gas transducer has dielectric backing on which upper surface there is made film heater in the form of at least one film element of rectangular shape with film contacts and gas sensitive layer with film electrodes. Dielectric backing is attached to case of transducer with side parallel to resistive element of heater. Film leads of heater and gas sensitive layer which are continuation of film contacts of heater and electrodes of gas sensitive layer are made on upper surface of backing. Electrodes of gas sensitive layer are arranged between film heater and opposite unattached side of dielectric backing. EFFECT: simplified manufacturing process, enhanced functional reliability. 4 cl, 1 dwg
