4 Mechanical Assembly
It is to be differentiated between measuring side and drive side of the sensor. The housing is fixed at the
drive side of the sensor.
The cable connection can influence the torque measurement.
At dynamic measurements, the measured value can be influenced by the inert masses of the
housing.
Measuring side – see corresponding data sheet.
4.1 Sensors up to 15 N·m
Sensors with nominal torques up to 15 N·m are very sensitive regarding overload; therefore
treat the sensors with great caution.
1. Connect the sensor electrically during the assembly and watch the signal; the measuring signal
may not exceed the limit values.
2. Align the arrangement before the parts are firmly connected.
3. Mount the sensor at the low torque resistance side first, then at the stationary side. (This
avoids impermissibly large torques from acting on the sensor.)
4. Counter-hold by hand, so that impermissibly large torques or disturbance variables can not act on
the torque sensor.
4.2 Flange Connection
Before the assembly, flanges must be cleaned with dissolver (e.g. acetone), no foreign particles may
adhere to them. The surface of the flange must indicate a evenness of at least 0.02 mm.
Tighten screws consistently. The flange may not slip while torque is applied (surface pressure), if
necessary use fitting bolts.
4.3 Shaft Connection
The shafts must be cleaned with dissolver (e.g. acetone) before the assembly, no foreign particles may
adhere to them.
The hub must fit corresponding to the connection.
4.4 Inside Square and Outside Square
The inside and outside square must be cleaned before the assembly. No foreign particles may adhere to
them.
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.
Caution at permutation of drive side and measuring side.
