Magtrol Torque Transducers are very reliable, providg high overload protection, excellent long term stability and high noise immunity. All transducer models employ our unique non-contact differential transformer torque measurg technology. This measurg technology offers many benefits, most notably that no electronic components rotate durg 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 staless steel shaft with smooth or spled shaft ends, an anodized alumium housg contag the guide beargs and an electronic measurement conditioner. The tegrated electronic circuit, Model TM 316 Torque Transducer supplied by sgle voltage, provides torque and speed signals without any additional amplifier. The transducer is a stand-alone measurg cha. onnections are made by means of a 6-pole male connector mounted on the housg. A removable alumium base, delivered as standard, allows fixed mountg of the transducer. Applications TM and TMHS Series Torque Transducers provide dynamic torque and speed measurement of: Propellers - aerospace, mare and helicopter Wdshield wipers, electrical wdows, starters, generators and brakes automobile dustry Pumps - water and oil Reduction gears and gearboxes lutches Motorized valves rills, pneumatic tools and other mache tools asic System onfiguration TORQU TRASUR Power Supply 20 to 32 V / 100 ma max.

3 A imensions Operatg Prciples The measurg system, based on the prciple of a variable, torqueproportional transformer couplg, consists of two concentric cylders shrunk on the shaft on each side of the shaft s deformation zone, and two concentric coils attached to the housg. oth cylders have a circularly disposed cocidg row of slots and rotate with the shaft side the coils. An alternatg current with the frequency of 20 khz flows through the primary coil. When no torque is applied, the slots on the two cylders fail to overlap. When torque is applied, the deformation zone undergoes an angular deformation and the slots beg to overlap. Thus a torque-proportional voltage is on the secondary coil. The conditiong electronic circuit corporated the transducer converts the voltage to a nomal torque signal of 0 to ±5 V. A low-pass filter (utterworth/2nd order), adjustable from 5 khz to 1 Hz, allows tung of the torque signal frequency limitation. An optical sensor reads the speed on a toothed path mached directly on the measurg system. The electronic conditioner outputs a frequency signal proportional to the shaft rotational speed. An active circuit compensates the zero and sensitivity temperature drifts with a tolerance of 0.1% / 10 K.

Several manufacturers provide adequate couplgs for both supported and suspended drive tra stallations. The criteria for selectg appropriate couplgs for torque measurement is as follows: High torsional sprg rate: nsures high torsional stiffness & angular precision (should be > 3 times the torque transducer stiffness) lampg quality (should be self-centerg & of adequate strength) Speed range alancg quality (accordg to speed range) Alignment capability The higher the speed of the application, the more care is required selectg the couplg and assemblg (alignment and balancg) the drive tra configuration.
