Precision torque sensor - 8661

This high precision torque sensor is designed for both static and dynamic measurements on non-rotating applications. It is particularly suitable for torque measurements on, for instance, extremely small electrical actuating drives and micro-mechanical actuator elements, or for measuring reaction torques e.g. on micro-motors. The high accuracy of measurement also makes this sensor ideal for use as a reference in many fields of industrial manufacture as well as laboratory research and development projects. Not containing any rotating parts, it requires no maintenance if properly used. The strain-gage 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. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function.

Precise, reliable measurements of both static and dynamic torques in either direction can be made with this range of sensors. This opens a wide range of possible applications to the user. These torque sensors are standard equipment in a wide range of industrial automation, quality control and automotive components industry applications, as well as in laboratories. Typical applications: Screwing technology — Checking and adjusting bolting tools such as torque limiting wrenches, screwdrivers — Testing bolted connections Measuring the drag torque of motors and pumps — Frictional torques of gears, bearings and seals — Testing torsion springs — Adjusting equipment in the automobile industry (sunroof, power windows etc.) Strain gauges are mounted on the torsion shaft of the sensor element, itself made of steel, connected to form a full bridge.

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 very short torque sensor model 8656 is contactless constructed. The torque is recorded by the torsion of the shaft using the strain gauge 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, up to 10,000 rpm is possible. 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 shaft is equipped with keyways in every measuring range, matching keys are included. If a key connection is not required, the key can be omitted. The torque is matched with suitable couplings, we recommend model 8690, safely transmitted.
