    The maintenance-free model 8652 torque sensor is used to measure constant and changing torques in both directions of rotation. The range from stationary up to continuous operation at high speeds of rotation is permitted.

    With the option of the two, switchable measuring ranges, it is possible to use a single sensor to measure even an unusually large range of torques with high accuracy. This saves refitting time; only one pair of couplings is needed, and the smaller measuring range has a high level of overload protection. The rotation speed pulses generated by the sensor also permit a direct determination of power.

    Typical applications include:

    1. Test beds for engines, turbines and gearboxes, extruders
    2. Machine building
    3. Drive equipment
    4. Aerospace engineering
    5. Automotive
    6. Product development
    7. Quality assurance


    The full bridge, consisting of four active wire strain gauges attached to the measuring shaft, converts the mechanical magnitude, torque, which causes a relative rotation between the two shaft ends, into a proportional electrical signal.

    Measuring electronics are integrated into the shaft. This digitizes the measured value at a high sampling rate and transmits it without contact to the stator. There it is again converted into an analog voltage and normalized. For the nominal torque of ± MN the sensor delivers ± 5 V (± 10 V, see option).

    TTL pulses are generated in order to measure the speed of rotation (standard) and the angular displacement (as an alternative to the rotation speed, see option). The power required by the measuring shaft is transmitted inductively, i.e. once again without contact.

    A control input can be used to check the function of the transmission of the torque signal. An analog voltage of either 0 V or + 5 V is present at the unloaded analog output of the sensor, depending on the level of the control signal.
