Terms
Measuring Side:
Mechanical connection of the torque sensor in which the torque to be measured is applied. Usually this
side has the smallest moment of inertia.
Drive Side:
Mechanical connection of the torque sensor on the opposite side of the measuring side, usually with the
largest moment of inertia. At static torque sensors the housing is fastened on this side.

Product Description
The sensor measures following static and dynamic measurements:
Torque
Speed
Angle
The installation position of the torque sensor can be chosen freely.
Caution: it is to be differentiated between measuring side and drive side, see data sheet of the sensor:

Mechanical Setup
The sensors consist of a torsion shaft. Depending on design, the mechanical connection possibilities are
executable with spline drive or square drive etc. The torsion shaft, applied with two strain gauge full
bridges, is bedded in a housing through ball bearings. For the signal transmission and/or the supply of the
strain gauge full bridges, a rotating transformer, according to the principle of a transformer, is arranged in
the sensor. For supply and measuring signal conditioning, electronics are integrated in the stator and the
rotor.
