TORQUE SENSOR |data acquisition systems|data logger|digital panel meter|vibration monitoring The HBM torque sensor is used in many branches of industry andresearch: plant supervision and process monitoring, motive power engineering and materials handling technology, test bench technology, quality assurance, as well as research and development. The torque sensor range offered by HBM includes torque measurement shafts and flanges, as well as a non-rotational torque sensor for measuring reactions. Signal transmission is effected with the help of slip rings or contactless. In addition, tested couplings are available together with torque measurement shafts. HBM also offers matching amplifiers and measurement technology software for processing and analysing measurement signals. The product range in this field is completed by in-house calibration to DKD standards. 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. |
