Torque transducers

The integrated, magnetic measurement system has been designed to overcome the effects of humidity, condensation, dust, oil and grease that can restrict the effectiveness of some optical measurement systems. 

The T40B family provides measuring ranges of up to 50Nm for various applications, while the T40FM range covers maximum range options to 80kNm. All benefit from an output pulse count over all ranges of 1024 pulses per revolution. This makes it possible to implement resolutions of up to 12 bits in any downstream electronics depending on the evaluation method such as pulse quadrupling. 

The reference signal is generated by a separate magnetic field that includes a sensor. This enables the integrated system to provide signals for integrating the rotational speed and angle of rotation. The direction of rotation is detected by two square-wave output signals at the stator that are electrically phase-shifted through 90°. 

The rotational speed measuring system has a high tolerance for application-related vibrations because the radial or axial distance between the sensor and the magnetic ring is up to 2.5mm. This allows full use to be made of the maximum rotational speed specified for the transducer, in conjunction with the rotational speed measuring system.
