DDU-rotor and DDU-stator constitute a sensor system for contact-free monitoring of rotating and rigid tool holders. The sensor system is based on DMS technology. The rotor continuously measures the torque values acting on the tool as well as the feed forces. The transmission of the energy supply and the measurement data to the attached measuring transducer is carried out inductively via an air gap located between the rotor and a stator (telemetrie).
Together with a measuring transducer, the DDU sensor system can be used in combination with CTM and Genior Modular monitoring systems.
