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

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.
