  • High speed high accuracy active force transducer
    Patent number: 5998742
    Abstract: A force transducer and method of measuring an applied force such as a weight of material, comprising a balance beam, said balance beam being supported at a preset position on a base at a fulcrum between its two ends, a voice coil actuator comprising an electrically conductive coil and a magnet, the coil being mounted on the base and the magnet being mounted on one side of the fulcrum of the balance beam, a counterbalance mounted on the second side of the fulcrum of the balance beam whereby said balance beam is generally unresponsive to low frequency vibration at the base, a beam position sensor for detecting beam movement from its preset position by a force applied to the beam, a control system associated with the sensor and coil and responsive to the sensor for supplying an electric current through the coil in an amount sufficient to maintain the magnet and thereby the beam at the present position, and a current detector for measuring the amount of current so supplied and thereby the amount of the applied fo
