DF series torque measuring flanges

The DF series torquemeters by the numbers

  • Maximum speeds of up to 25,000 rpm
  • Accuracy class: 0.04% F.S. (full scale)
  • A-D converter: 24 bit
  • D-A for analogue output: 16 bit
  • Total sampling rate: 25 kHz
  • Operating temperature range: 0…85°C
  • Rated gap distance: < 4 mm
  • Limit torque: 300%
  • Customer-specific measuring ranges on request

The DF series torque measuring flanges feature an innovative measuring element in combination with digital multi-channel telemetry. This enables an extremely wide bandwidth of installation and measurement arrangements. The torquemeter is unique in that it features three genuine strain gauge amplifiers electronics of the rotor. The additional overflow channel transmits measurement values of up to 300% of the nominal torque. The rotor temperature is also signaled. The flange dimensions of the DF series conform to the DIN norm and are compatible with existing systems.
