  • an embodiment of the closing device which is characterized in that at least two sensors are provided, so that the relative position between the drive and driven rotor not only in axial alignment, but also with respect to the rotational position of the rotors is detectable to each other. In this way, many data of the closing process can be detected accurately.
  • closing device which is characterized by a signal processing device which processes the data of the at least one sensor. In this way, the possibility exists to prepare the data already at the place of origin for later use.
  • the closing device which is characterized in that it comprises a transmitter for wireless transmission of the data of the at least one sensor, which allows the transmission to a receiver.
