14. DUCER LOAD Wm Be COUPLING COUPLING FLE SIBLE EARTH STRAP 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 Single membrane with a degree of compliance would be more appropriate coupling Flexible mounting Never use a solid coupling to connect a RWT series transducers Torque Transducer For Transducers below 1Nm or 10lbf in or if the application requires the body to be rigidly mounted then it is recommended that double couplings should be used at each end to compensate for any misalignment of the input output shafts and the system designed to eliminate any end loads on the transducer shaft For applications where end loads cannot be avoided please consult the sales department for advice prior to ordering When using a pulley or pulleys it is recommended a bearing block or blocks should be used to ensure bending loads are no
