Cable Capacitance Monitor / Calibration Capacitor

  • This monitor can continuously measure capacitance of a covered cable in on-line water bath, which is manufacutured by continuous extruding machine.
  • Cable capacitance control is available by outputting control voltage.
  • Cablibration for Cable Capacitance Monitor is available by Calibration Capacitor (Option).
  • By RS-485 interface, intergrated data management can be done.(Option)
