STRAIN-GAUGE SENSOR Russian patent published in 2014 - IPC G01B11/16 G01L1/24 

FIELD: measuring instrumentation.

SUBSTANCE: strain-gauge sensor includes loading element in the form of a hollow cylinder 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. Optic axis of pieso-optic converter coincides with the cylinder axis and is perpendicular to measured deformation plane, loading element is a continuous hollow cylinder out of tensile material with wall thickness ensuring required elasticity of loading element in direction of deformations measured and determining sensitivity of strain-gauge sensor sealed at the ends and featuring hard lugs on the outside for attachment of the sensor to a monitored object and transmission of object deformation to stress-optical element.

EFFECT: enhanced functional capabilities of device.
