ABSTRACT:
A strain gauge pick-up for the measurement of a test piece. This pick-up ludes two tapping points mounted on a pair of rigid elbow members. The elbow members are spaced a predetermined distance apart, and their spacing varies as the tapping points are applied to the test piece. The elbow members are attached to the deflection plate which flexes as the spacing between the elbow members changes. A wire strain gauge is positioned on the deflection plate and senses the flexing motion. Several pick-ups can be integrated so that their tapping points are substantially colinear.
