DEFINITION

Classification: 73/763

Specified electrical sensor or system:

(under subclass 760) Subject matter wherein the stress or strain is sensed by an electrical transducer and (a) either succeeding circuitry or (b) specific transducer structure and identifiable load applying structure.

(1) Note. Mere nominal recitation of a "strain gage" with other mechanical structure is not classified herein but rather in the appropriate subclass indented under 760.

(2) Note. Recitation of specific transducer structure absent identifiable load applying structure is classifiable in the appropriate electrical transducer class.
