  • Page 17: Chapter 4 Function Principle

    Function principle Function principle The measuring coil of the eddy current sensor (for example EZ 1050 or EZ 1080) is connected to an oscillator circuit in the converter through a shielded connection cable. The oscillator circuit generates a high-frequency signal resulting in a high-frequency magnetic field around the tip of the eddy current probe.

  • Page 18: Sensor Supervision

    Function principle Note If installing a calibrated measuring chain at a different measuring point, ensure that the target material of this point is the same as of the previous point. Otherwise, recalibrate the converter on the new target material. Sensor supervision The EZ 1000 checks the connected sensor by supervising the signal voltage.
