Obere Schloßstr.131 07172 / 93730-0 LORENZ MESSTECHNIK GmbH Fax 07172 /93730-22 73553 Alfdorf 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. -

Obere Schloßstr.131 07172 / 93730-0 LORENZ MESSTECHNIK GmbH Fax 07172 /93730-22 73553 Alfdorf 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. -
