LOAD CELL AND TORQUE SENSOR – X/Y/Z-Model 8565

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.

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.

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.

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.
