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.
- 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. The electrical power excitation for the wire strain gauge full bridge and the transmission of the measured signal is provided through a high-quality slip-ring system between the stator and the rotor.
For a clockwise torque, the measurement signal is positive, and it is negative for a counterclockwise torque.
The sensor for the optionally available angle measurement for the square shaft versions is fitted with an additional pulse-generating disk.
With the aid of a second encoder track, displaced by 90°, allows the subsequent evaluation units to perform 4-fold edge evaluation. This allows significantly improved resolution to be achieved. The offset track makes it possible to detect the direction of the rotation.
The characteristic parameters for the sensors are standardized in order to reduce the effort required to check a connected amplifier or to exchange the sensor.
