    General Description Construction and Functional Principle of the Reaction Torque Sensor The special, patented construction of Kistler reaction torque sensors is distinguished by the fact that the sensor is integrated under high axial preload between a preload screw and a nut. The torque is thus transferred by friction onto the shear-sensitive quartz disks.

  • Page 32: Basic Circuitry And Connections For The Measuring Chain

    Installation and Startup Basic Circuitry and Connections for the Measuring Chain When the applied torque changes, the reaction torque sensor produces an electric charge. The charge signal is converted into a proportional output voltage by the charge amplifier, which can then be measured and recorded by an electronic evaluation system.

Operation 6.1 Charge Amplifier Settings For reaction torque sensors Type 9329A … 9389A, we recommend that you use a charge amplifier with sensitivity adjustment (e.g. Type 5015A...). Please consult the relevant operating instructions for details concerning the settings for the charge amplifier.

  • Page 34: Measuring Signal Resolution

    Operation Measuring Signal Resolution Resolution is the smallest possible change to the measurand which can be measured by the system. It is determined by the signal/noise ratio at the signal output of the charge amplifier. For laboratory charge amplifiers, the resolution at the highest gain is typically.

  • Page 36 Operation Start the measurement with <Operate>. The fluctua- tions of M can now be measured with high resolution, since the dynamic threshold is ≈0,6 mN·m. This means that a ΔM of 0,6 mN·m will produce an output voltage of ≈600 mV (scaling 1 mN·m/V). The resolution which can be achieved is thus ≈1 : 160 000 ! 0,6 mN·m : 100 N·m...

The capacitance, and thus the length of the connecting Cable capacitance cable, has no influence on the measuring result when Kistler special cables and Kistler charge amplifiers are used.

Example: when an additional bending mo- ment acts on a force sensor. Drift Unwanted changes in the output signal independent of the measurand as a function of time.

    Reaction Torque Sensors Type 9329A, 9339A, 9349A, 9369A, 9389A This requirement is found mainly in repetitive measure- ments in production processes, where good repeatability is usually sufficient for process monitoring. Accuracy primarily plays only a subordinate role, when measurements can be directly related to conforming/nonconforming parts.

  • Page 52: Influence Of Temperature

    Annex In their dynamic behavior, piezoelectric sensors are superior to all other measuring methods. Their high rigidity results in the highest possible natural frequencies. Piezoelectric sensors are thus ideal for measuring measurands which change rapidly over time. Their dynamic behavior is thereby largely determined by the surrounding structure.
