Page 4: Read First
Read First Safety and Caution Symbols Caution: Injury Risk for Persons Damage of the Device is possible Note: Important points to be considered Intended Use Torque sensors are intended for the measurement of torques. This measurand is further suitable for control tasks. -
Page 5: Term Definitions
Term Definitions Terms Measuring Side: Shaft connection in which the torque to be measured is applied. Usually this side has the smallest moment of inertia. Drive Side: The shaft end on the opposite side of the measuring side with the larger moment of inertia. At this type of torque sensors the housing is fastened on this side. -
Page 6: Mechanical Assembly
Mechanical Assembly Caution: During the assembly inadmissibly large forces may not act on the sensor or the couplings. At small torques (< 20 N·m) connect the sensor electrically during the assembly and observe the signal, the measurement signal may not exceed the limit values During the assembly the sensor must be supported to protect it from falling down. -

Page 8: Extension Cable
Extension Cable Caution: depending on bridge resistance and wire cross section, the measuring cable length enters into the characteristic value of the sensor. Running of Measuring Cables Do not run measuring cables together with control or heavy-current cables. Always assure that a large distance is kept to engines, transformers and contactors, because their stray fields can lead to interferences of the measuring signals. -
