STRAIN-GAUGE CONVERTER Russian patent published in 2014 - IPC G01L1/24 G01D3/28 G12B7/00

Abstract RU 2530466 C1

FIELD: measuring instrumentation.

SUBSTANCE: strain-gauge converter includes loading element attached to the monitored object, pieso-optic converter converting tension value in stress-optical element attached in preloaded state into electrical signal, and signal processing unit. Loading element is a plate with cylindrical hole where stress-optical element of cylindrical form is clamped adjustably in direction of measured deformations by two rods made of material with thermal expansion factor larger than respective factor of the plate. Rod length is designed so as to ensure independence of preloading compression from temperature.

EFFECT: enhanced measurement accuracy, simpler device design.
