DEFINITION

Classification: 73/862.474

Resistance strain gage:

(under subclass 862.473) Subject matter wherein the determination is made by measuring a change in electrical resistance of a sensing means comprising an electrical conductor or semiconductor that is stressed by the deflection or the distortion of the elastic member.

(1) Note. For the purposes of this subclass, a disclosure of strain detecting means affixed to a surface of the elastic member is presumed to be of the resistive type unless otherwise stated.
