RESISTIVE STRAIN-GAUGE FORCE TRANSDUCER Russian patent published in 2013 - IPC G01L1/22 

FIELD: measurement equipment.

SUBSTANCE: resistive strain-gauge force transducer includes an elastic element made as an integral part of a support ring. The elastic element is provided with four through holes with transverse slots in a lateral edge. Resistive strain gauges are arranged on flat surface of the elastic element above through holes. Width of flat surface of the elastic element in location places of resistive strain gauges is variable and determined by the following mathematic expression: where b - maximum width of flat surface of the elastic element; h_min -minimum thickness of surface of the elastic element above the through hole; l - length of working part of the elastic element; X_T - coordinate of the resistive strain gauge; r - through hole radius.

EFFECT: increasing sensitivity of a resistive strain-gauge force transducer and improving measurement accuracy of low pressures.
