STRAIN-GAGE TRANSDUCER

摘要

FIELD: physics.;SUBSTANCE: proposed transducer comprises load secured on controlled element and strain-gage transducer to convert voltage across stress-optical element into electric signal, and signal processing unit. Load is made up of plate to concentrate strain at stress-optical element. Stress-optical element is fixed in said plate as-stressed so that initial stress force acts in two mutually perpendicular directions. Note that stress-optical element is fixed at plate thinned center by means of Morse taper. Note also that, additionally, two mutually perpendicular through cuts are made not corrupting plate integrity, cuts axes being directed at 45° to loads axis. Cuts axes are aligned with that of taper hole for stress-optical element attachment.;EFFECT: higher sensitivity, thermal compensation.;5 cl, 1 dwg
