Product image DATAFLEX 42,1000 Dual-range torque sensor up to 1000 Nm

DATAFLEX® Torque measuring shaft

for torques up to 20,000 Nm / Torque sensor

Dual-range torque sensor for measuring torque and speed

Precise measuring of torque and speed is an indispensable part of modern drive technology with its variable and dynamic drives. The DATAFLEX torque sensor has two measuring ranges calculating four parameters at the same time: torque, speed, rotation angle and rotation direction. The family of precision measuring shafts is available in eleven sizes from 10 Nm to 20 kNm.

The torque is measured via renowned wire strain gauges technology, combined with state-of-the-art electronic components. The signals are contactlessly measured by torque sensors with a high resolution of 24 bits achieving an accuracy of 0.1 % of the final value.


  • Dual-range sensor 5:1

  • Inaccuracy 0.1 %

  • Integrated speed measurement

  • Direction signal

  • Output signal ±10 volts

Torque measuring shaft with two measuring ranges

A simple touch of a button switches the torque measuring shaft to a second measuring range amounting to one fifth of the nominal value. This allows significantly smaller torques to be precisely measured without having to change the test setup. In addition the measuring system has an encoder for calculating the speed. It provides two 90° phase-shifted signals and a scalable DC voltage for the speed.

Applications of DATAFLEX torque measuring shaft:

  • machine monitoring
  • process control
  • test bench technology

High-power torque sensors

If requested, we manufacture customised torque sensors and torque measuring shafts for large measuring ranges from  20 kNm to 500 kNm. In this context key parameters such as measuring range, size, length and kind of connection can be adjusted to the specifications. The torque is measured contactlessly so that bearings are not required.

Apart from customised torque sensors KTR provides special solutions, for example with couplings equipped with torque measuring technology which require no or only few amendments of the customer setup.
