TORQUE METER Russian patent published in 1996 - IPC

FIELD: measurement technology. SUBSTANCE: torque meter has measurement bridge incorporating resistance strain gauges 1-4, power supply source 5, current collecting contacts 6-11, amplifiers 12 and 13, divider 14. Current collecting contact 6, vertexes of supply diagonal of bridge, current collecting contact 7 are connected in series and linked to output of source 5. Vertexes of supply diagonal of bridge are connected through current collecting contacts 8 and 10 to inputs of amplifier 13. Vertexes of measurement diagonal of bridge are connected through current collecting contacts 9 and 11 to inputs of amplifier 12. Outputs of amplifiers 12 and 13 are connected to input of divider 14 which is output of torque meter. EFFECT: enhanced functional stability and reliability. 1 dwg
