4.1.2 Example for Assembly with Radial Clamping Hub
4.2
Examples for Torque Sensors without integrated Couplings
By special adapters, the sensor can be connected to any connection element.
Disturbance variables such as
•
radial misalignments,
•
angular misalignments,
•
axial
misalignments
always need to be balanced (double-jointed coupling).
4.2.1 Use of Centre Bore
Each part which is led-through the torque sensor means a torque shunt.
•
By this, a part of the torque is led-through passed the sensor.
•
This proportion is not measured
→
the shunt must be small compared to the measured torque.
The large centre bore is suitable for the lead-through of
•
hydraulic
hoses
•
pneumatic
hoses
•
rods
Please note
•
The lead-through part may not acquire torque
which will influence the measurement result
•
The shunt torque for the transposition of the led-
through parts must be very small against the
applied torque.
