Potentiometric angle of rotation sensor - 8820

Incremental rotation sensors are used wherever displacement, positions or speeds have to be measured accurately. They are therefore important interfaces between the mechanical and electronic parts of a machine. Mechanically robust, electrically reliable and resistant to extreme ambient conditions; these are the outstanding properties offered by this sensor. Typical applications include —Machine tools —Wood and plastic machining —Textile machines —Lifts —Door systems —Paper machines —Drive equipment —Assembly and handling equipment —Packaging machines —Scales —Test machines —Conveying equipment —Doors and gates Specific characteristics —Degree of protection IP65, all-around —Robust —High resistance to interference —Rotary speed sensor: 60 pulses/turn (standard) —Angular displacement sensor: up to 3600 pulses/turn —Detection of rotation direction (channels A and B) —Reference pulse (channel N) —Special versions on request

This high-precision torque sensor is designed for both static and dynamic measurements on non-rotating parts. The 10mm diameter throughhole can be used to feed parts such as cables or Bowden cables through the sensor. The mounting flanges contain threaded holes and through-holes so that the sensor can be fitted at either end. With no rotating parts, this sensor needs no maintenance when used correctly. The modular design of this strain-gage sensor allows precise configuration for the desired application. With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ± 10 V that is proportional to the torque. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function. With the USB option, in addition to the voltage output, the measurement function is available via USB as well.

The compact torque sensor model 8655 with standard square is contactless constructed. The torque is recorded by the torsion of the shaft using 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. The direction of rotation can be seen from the potential of the output voltage, clockwise rotation corresponds to positive output voltage, counterclockwise rotation the voltage level is negative. The standard square enables simple integration into existing systems or devices, additional components such as couplings are not require. To record the speed and angle of rotation, the sensor can optionally be equipped with an incremental disc with 400 increments. This speed / angle signal is available as a TTL output signal.

This high-precision torque sensor can be used to perform both static and dynamic measurements on non-rotating parts. The internal and external square drive design make this sensor especially easy to fit in existing or new screw-fitting applications. Quality assurance and monitoring of screw-fastening tools are just two applications that can take full advantage of sensor features such as USB port, built-in amplifier and side-load absorbing bearings. With no rotating parts, this sensor needs no maintenance when used correctly. Available accessories include mounting brackets and flange adapters, which enable quick, easy and practical integration of the sensor into existing or newly developed setups and test benches. The strain-gauge based sensor’s modular design allows precise configuration for the desired application. With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ± 10 V that is proportional to the torque.
