    Telemetry System Manual Vers. 2.7 Stator Head The CAEMAX stator head provides noncontact energy supply of D transmitters (SCTs) by inductive coupling: An alternating magnetic field from the stator head induces voltage in the secondary coil on the device. This induced voltage is used for supply of the D transmitter unit (SCT).
  • Page 66 Telemetry System Manual Vers. 2.7 Please note: The operating point, i.e. the optimum frequency of the alternating electrical field, is automatically set and readjusted by the stator electronics. The operating point of the system is dependent on a variety of factors. If the stator is put into operation for the first time, the determination of the optimum frequency may take several minutes.
