TENSORESISTOR FORCE TRANSDUCER Russian patent published in 2011 - IPC G01L1/22 

FIELD: physics.

SUBSTANCE: tensoresistor force transducer has an elastic member with a rectangular cross-section with four through holes in the side face and slits on the lower sides of the holes over which there is a flat surface where tensoresistors are mounted, a connection hole for the force-measuring element (rod) in between pairs of holes. Two platforms with heat-compensation resistors, having a brand-like profile, lie over a support ring in the same plane as the elastic member protruding over the support ring by a height defined by the following mathematical expression: H≥d+h, where d is the diameter of the through holes, h is the smallest distance between the flat surface of the elastic member and the through holes. The elastic member and the support ring with platforms are integral.

EFFECT: stability of parameters and maximum sensitivity of the tensoresistor force transducer with minimum force on the elastic member, high functionality of the structure as a whole.
