Each model has an tegrated conditiong electronic module providg a VC to ±1 VC torque output and an open collector speed output. 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. Each transducer consists of a hardened staless steel shaft with smooth, spled or keyway shaft ends, an anodized alumium housg contag the guide beargs and an electronic measurement conditioner. The tegrated electronic circuit, supplied by sgle C voltage, provides torque and speed signals without any additional amplifier. The transducer is a stand-alone measurg cha. Connections are made by means of a 6-pole male connector mounted on the housg. A removable alumium base (delivered as standard with TM and TMS models, and as an option for TMB transducers) allows fixed mountg of the transducer. To provide customers with several price/performance options, Magtrol offers three torque transducer models: basic model (TMB Series), high accuracy (TM Series) and high speed with high accuracy (TMS). 218 MATRO ue to contual product development, Magtrol reserves the right to modify specifications without forewarng.

2 OPERATIN PRINCIPES The measurg system, based on the prciple of a variable, torque proportional 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. Both cylders have a circularly disposed cocidg row of slots and rotate with the shaft side the coils. An alternatg current with the frequency of 2 kz 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 VC to ± 5 VC. A low-pass filter (Butterworth / 2nd order), adjustable from 5 kz to 1 z, allows tung of the torque signal frequency limitation. An optical sensor reads the speed on a toothed pattern 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.1 % / 1. EECTRICA CONIURATION ig. 3: TM's electrical put and output SUPPORTE & SUSPENE INSTAATIONS Power Supply 2 to 32 VC / 1 ma (max.) Test Torque to ±1 VC (max.) Speed TheTMB Series is dedicated for use a basic configuration or for low speed applications. The TMB Series ranges from TMB 33 (.5 N m) to TMB 313 (5 N m). ue to dedicated low speed usage,the TMB Series is delivered without base mount however, a base is available as an option. The TM Series ranges from TM 39 to TM 317 and can also be stalled without the base mount a suspended configuration. This configuration is only allowed for low speed measurment. The benefit of this configuration is the use of a sgle element couplg, creatg a shorter drive tra.

10 SYSTEM OPTIONS AN ACCESSORIES COUPINS When Magtrol TMB, TM and TMS Series Torque Transducers are to be mounted a drive tra, double-element miature couplgs are the ideal complement, although sgle-element couplgs can be used for low speed applications. The criteria for selectg appropriate couplgs for torque measurement is as follows: igh torsional sprg rate: Ensures a high torsional stiffness and angular precision Clampg quality (should be self-centerg and of adequate strength) Speed range Balancg 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.
