Each model has an integrated conditioning electronic module providing a ±5 VDC (±10 VDC) torque output and an open collector speed output. Magtrol Torque Transducers are very reliable, providing high overload protection, excellent long term stability and high noise immunity. All 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 three torque transducer models: basic model (TMB Series), high accuracy (TM Series) and high speed with high accuracy (TMHS Series). Each transducer consists of a hardened stainless steel shaft with smooth, splined or keyway shaft ends, an anodized aluminium housing containing the guide bearings and an electronic measurement conditioner. The integrated electronic circuit, supplied by single DC voltage, provides torque and speed signals without any additional amplifier. The transducer is a stand-alone measuring chain. Connections are made by means of a 6-pole male connector mounted on the housing. A removable aluminium base (delivered as standard with TM  Series and TMHS  Series models, and as an option for TMB  Series transducers) allows fixed mounting of the transducer. © 2023 MAGTROL | Due to continual product development, Magtrol

TM 300 Series | In-Line Torque Transducer - 2

TM 300 SERIES OPERATING PRINCIPLES ELECTRICAL CONFIGURATION The measuring system, based on the principle of a variable, torque proportional 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. Both cylinders have a circularly disposed coinciding row of slots and rotate with the shaft inside the coils. An 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...

a) Center according to: ISO 6411 - A1 / 2.12 (for TM 301-303) DIN 332 - D M4 (for TM 304-308) b) Centering seat CAUTION: MAGTROL has redesigned the fixation for its small torque transducers (TM301 ... TM 308). The new housing allows installation of the torque transducer from the bottom as before, but also allows installation from the top. It also integrates a centering key underneath its housing. The old fastening system (from the bottom only) is still available as an alternative option. NOTE: Dimensions are the same for every series (TM 300 Series, TMHS 300 Series). Original dimensions are...
