Abstract
A solid state sensor element is a flat device having a film resistance thermometer on one face and a pair of spaced apart conductors on the other. The element is used for measuring selected properties of a material or the surrounding atmosphere and normally the spaced conductors are covered by a coating of a material which is electrically responsive to variations in a selected parameter of the ambient atmosphere.
Claims17
A solid state sensor element comprising a planar substrate of a material selected from the group consisting of electrically insulating material and material having electrically insulating faces, the substrate having, on one face thereof, a first pair of electrical connection points and a temperature responsive electrically conducting path extending between forming a resistance thermometer element, and, on the opposite face of the substrate, a second pair of connection points and a pair of physically separate electrical conductors connected respectively to said second pair of connection points, the electrical conductors having between them an elongate gap of substantially constant width.
