Magtrol Torque Transducers are very reliable, providing high overload protection, excellent long term stability and high noise immunity. ll transducer models employ our unique non-contact differential transformer torque measuring technology. This measuring technology offers many benefits, most notably that no electronic components rotate during operation. To provide customers with several price/performance options, Magtrol offers two torque transducer models: high accuracy (TM series) and high speed with high accuracy (TMHS). ach transducer consists of a hardened stainless steel shaft with smooth or splined shaft ends, an anodized aluminium housing containing the guide bearings and an electronic measurement conditioner. The integrated electronic circuit, Model TM 316 Torque Transducer supplied by single voltage, provides torque and speed signals without any additional amplifier. The transducer is a stand-alone measuring chain. onnections are made by means of a 6-pole male connector mounted on the housing. removable aluminium base, delivered as standard, allows fixed mounting of the transducer.

3 imensions OPRTIG PRIIPLS The measuring system, based on the principle of a variable, torqueproportional transformer coupling, consists of two concentric cylinders shrunk on the shaft on each side of the shaft s deformation zone, and two concentric coils attached to the housing. oth cylinders have a circularly disposed coinciding row of slots and rotate with the shaft inside the coils. n alternating current with the frequency of 20 khz flows through the primary coil. When no torque is applied, the slots on the two cylinders fail to overlap. When torque is applied, the deformation zone undergoes an angular deformation and the slots begin to overlap. Thus a torque-proportional voltage is on the secondary coil. The conditioning electronic circuit incorporated in the transducer converts the voltage to a nominal torque signal of 0 to ±5 V. low-pass filter (utterworth/2nd order), adjustable from 5 khz to 1 Hz, allows tuning of the torque signal frequency limitation. n optical sensor reads the speed on a toothed path machined directly on the measuring system. The electronic conditioner outputs a frequency signal proportional to the shaft rotational speed. n active circuit compensates the zero and sensitivity temperature drifts within a tolerance of 0.1% / 10 K.

Several manufacturers provide adequate couplings for both supported and suspended drive train installations. The criteria for selecting appropriate couplings for torque measurement is as follows: High torsional spring rate: nsures high torsional stiffness & angular precision (should be > 3 times the torque transducer stiffness) lamping quality (should be self-centering & of adequate strength) Speed range alancing quality (according to speed range) lignment capability The higher the speed of the application, the more care is required in selecting the coupling and assembling (alignment and balancing) the drive train configuration. Your Magtrol sales representative can assist you in choosing the right coupling for your transducer.
