Description
Magtrol’s In-Line Torque Transducers provide extremely
accurate torque and speed measurement over a very broad range.
Each model has an integrated conditioning electronic module
providing a 0 to ±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 accuracy
(TMB series), high accuracy (TM series) and high speed with
high accuracy (TMHS).
Each 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, 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 and TMHS models, and
as an option for TMB transducers—allows fixed mounting of
the transducer.
