  • Patent number: 4637263
    Abstract: A multi-component force and torque measurement cell which has strain gauges connected in each branch to a constant current source forming half-bridge circuits. These are arranged on a measurement spring with defined force introduction for longitudinal and transverse forces as well as torques in the strain direction of the measurement spring. The strain gauges are subdivided into two series circuits each having half the strain gauges and one constant current source connected at both ends to each other and to the ground. The measured voltages can be tapped between sequentially corresponding connecting points of immediately adjoining strain gauges in both series circuits.
