Delivery: ex stock | Warranty: 24 months rotating, contactless With mounting block and couplings Highlights ■ Measurement ranges of 0 ... 0.02 N-m to 0 ... 1000 N-m ■ Very low linearity error < ±0.05 % F.S. ■ Refresh rate 2000 measurements/s ■ Speed and angle measurement up to 2000 increments ■ Dual range in different graduations ■ Shaft end with keyway ■ USB port including software ■ Machinery and plant engineering ■ Electric motor test ■ Suitable for use in all types of test bench The non-contact torque sensor type 8661 works according to the strain gage principle. Thanks to the inductive and optical transmission of the signals, the sensor is maintenance-free, the signals are digitized directly on the shaft and made available by the evaluation electronics as a voltage signal or via USB. Thanks to the high-quality bearing, depending on the measuring range, up to 25,000 rpm is possible. The bidirectional voltage output from -10 V ... +10 V allows the direction of rotation to be identified very easily. To record the speed and angle of rotation, the sensor can optionally be equipped with different number of increments, up to 2000. This speed / angle signal is available as a TTL output signal. The free DigiVision Light software is available in connection with USB, alternatively drivers for LabVIEW and DASYLab are ready for download. Connection cables in various lengths, metal bellows couplings and mounting blocks are available for integration in customer-specific systems. burster Sensors and Process Instruments - Technical changes reserved.

12-pin connector or USB (Option, USB connection cable included) For optimum compensation of misalignment we recommend torsionally free metal bellow couplings. They are characterized by their excellent torsional stiffness during torque load and their low restoring forces. The couplings are optionally with keyways available. For further information please see accessories data sheet 8695. If the sensor needs to be replaced, the locating pin speeds up replacement, avoiding the need for laborious realignment. This can be useful especially when the sensor is only used occasionally in the load path....

The sensor with two measuring ranges corresponds to its dimensions of the standard version, but has two separately calibrated measuring ranges. The measuring ranges are switched within <50 ms, even during measurement operation, by applying the operating voltage to pin L or via USB. For angular displacement measurement (or direction detection), both channels need to be evaluated. To achieve the maximum angular resolution, four-edge decoding must be used to read both the rising and falling edges. For instance an angular resolution of up to 0.045° can then be achieved with an encoder disk having...
