Rotary Torque Transducer Installation Guide
it is recommended that the bodyof the transducer is not rigidly mounted but restrained
from rotation using a strap or straps connected to thetapped holes in the end plates. Couplings should be usedto allow for angular misalignment while the transducer
shaft takes up any parallel misalignment. Care should be
taken not to induce any end loads or bending moments to
the shaft, as these may induce inaccuracies to the torque
measurement and in extreme cases damage the transducer. To get the best from your RWT310/320 Series or E200Series Rotary Torque Transducer it is essential that it is
correctly installed.To avoid damaging the transducer during installation itis highly recommended that it is electrically connected
and working during this process so that any torque
overloads due to handling can be monitored.For rotary
torque transducers Should rapid variations in torque need to be measured
in detail e.g. torque fluctuations in gearboxes or multi
vane pumps then it is recommended using torsionally
rigid couplings fitted at both ends of the transducer
shaft such as single membrane couplings and that these
are correctly selected for the transducer rating and speed.
An undersized coupling will not transmit the torque while
the high inertia of an oversized coupling can result in
instantaneous peak torques far in excess of the measured
torque. Alternatively, for lower bandwidth applications,
where it is more important to measure the 'average'
torque rather than fast torque fluctuations, then couplings
with a degree of compliance would be more appropriate. Singlemembrane couplingDoublemembrane coupling Never use a solid coupling to
connect a RWT310/320 Series
or E200 Series Rotary Torque
Transducer.For rotary torque
transducers with torque ranges less than 1Nm (10lbf.in.), or rigidly mounted torquetransducers, it is recommended that double couplings should be used at each end to compensate for any
misalignment of the input/output shafts. The system should be designed to eliminate any end loads on the
transducer shaft. For applications where end loads cannot be avoided please consult our Sales Department
for advice prior to ordering.
