Torque Sensor
Model 8627, 8628, 8632
4. Mechanical Assembly
Caution: During the assembly inadmissibly large forces may not act
on the sensor or the couplings. At small torque (< 20 Nm) connect
the sensor electrically during the assembly and observe the signal,
the measurement signal ma not exceed the limit values.
During the assembly the sensor must be supported to protect it from
failing down.
It is to differentiated between measuring side and drive side of the sensor. The
housing is fixed at the drive side or of the sensor.
Caution at permutation of drive side and measuring side.
►
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 Nm
Sensors with nominal torques up to 15 Nm are very sensitive regard-
ing overload; therefore treat the sensor 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 distur-
bance variables can not act on the torque sensor.
