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.
