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.
Low Torque Resistance Side:
The shaft of the arrangement (drive, load) which can be turned considerably smaller with torque than the nominal
torque of the torque sensor M << M

Product Description
The sensor measures static and dynamic torques. The mounting position of the torque sensor is horizontally.
Caution: it is to be differentiated between measuring side and drive side, see data sheet of the sensor:
2.1
Mechanical Setup
The sensors consist of a torsion shaft with round shaft ends. 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.
