DF plus series torque measuring flanges

The torque measuring sensors of the DF plus series in figures

  • Accuracy class ≤ ±0.04 % F.S.
  • Max. Speed up to 25,000 rpm
  • A/D converter: 24 bit
  • D/A for analog output: 16 bit
  • Sum sampling rate: 25 kHz
  • Operating temperature range: 0…85 °C
  • Customized measuring ranges on request
  • DIN flange dimensions combined with compact design
  • No stator ring

The innovative design of the DF plus series torque measuring flanges, featuring standardized DIN dimensions and a ringless stator, enables an extremely wide range of installation and measurement configurations. A unique feature of the DF product family is the additional overload channel, which transmits measured values up to 300% of the rated torque. Rotor temperature and debug values can also be transmitted. The system is configured via a modern and intuitive website. The DF plus series systems are available in rotating and non-rotating (RTS) versions.
