FORCE SENSOR Russian patent published in 1996 - IPC

FIELD: measurement technology. SUBSTANCE: force sensor includes membrane, case joined to restoring member in the form of body of revolution with bent ring with cylindrical power input and reference shells. Butt of restoring member have under-resistor bosses carrying resistance-strain gauges. Conjugation planes of bent ring with mentioned shells are relatively displaced along action line of force by specified value determined by mathematical dependence taking into account geometric dimensions of elements of sensor, physical parameters of material of resistance-strain gauges and of elements of sensor and transfer ratio of sensor. EFFECT: improved reliability of force sensor. 1 dwg
