DEFINITION

Classification: 73/774

Specified sensor structure:

(under subclass 763) Subject matter wherein the stress or strain sensor structure is particularly described.

(1) Note. Mere nominal recitation of a transducer or transducer type is insufficient for classification herein. Particular structural features of the sensor must be recited.

(2) Note. Stress or strain sensors without either circuitry or mechanical means for coupling stress or strain related forces are not classified herein, but are classified in the

appropriate electrical element class (e.g., resistor).
