The HBM torque sensor is used in many branches of industry and Many measurement tasks in the field of industrial test bencher and automatic production/assembly processes can be solved very simply and reliably with the MVD 2555. Force, pressure, displacement and the torque sensor based on different technologies can be connected to the carrier frequency amplifiers which are particularly stable and insensitive to interference. A Schaevitz servo accelerometer is a closed-loop torque balance system. A pendulous mass develops a torque proportional to the product of its mass unbalance and the applied acceleration. Motion of the mass is detected by a position torque sensor whose output signal is applied to an electronic amplifier. The output current from the servo amplifier is applied to a torque motor, which then develops a torque equal but directly opposed to the inital torque of the pendulous mass. Thus the mass stops moving, assuming a position minutely differing from its original position before acceleration. The current through the torque sensor motor is accuratley proportional to input acceleration, and then passed through a stable resistor, an accurately proportional output voltage is developed.
