(ZA9408200-A)      Catalytic detector for a flammable gas comprises a substrate and a sensing structure suspended from the substrate. The substrate includes a heating element, a temp. sensing element in the form of a layer-deposited electrically conductive track terminating in at least two electrically conductive leads and a catalytic bead associated with the temp. sensing element. That portion of the substrate which is directly beneath the sensing structure being etched away so as to isolate thermally the sensing structure, and the temp. sensing structure being supported by the bridging leads. Also claimed is a method of mfg. a catalytic gas detector.    USE -   Mfr. of catalytic gas detectors used in continuous monitoring of methane.    ADVANTAGE -   The catalytic detector uses bridging leads as supports to enhance simplicity of mfr., whilst strength and flexibility of platinum leads gives greater resilience.
