SENSITIVE ELEMENT OF GAS ANALYZER Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: proposed element has heating spiral in the form of hollow cylinder formed by turns of cast microwire presenting conducting conduit in glass or ceramic insulation. Turns of microwire on inner and outer surfaces of cylinder are interconnected by monolithic layer of insulation material. Monolithic layer on outer surface of cylinder displays roughness greater than roughness of monolithic layer on inner surface of cylinder. EFFECT: increased stability of thermal-technical characteristics of sensitive element in wide range of operational temperatures, optimization of dependence of output signal of sensitive element on measured characteristics of gas atmosphere. 2 cl, 2 dwg
