Electromagnetic Guidance NS-CPC Sensor

Overview

A maintenance-free sensor
which can be used long term in harsh environments.

The NS-CPC sensor continuously detects the strip (steel sheet and metal plate) edge positions using electromagnetic induction and outputs any discrepancy in the strip center position as a deviation signal.
Because it uses electromagnetic induction, it is not affected by dust, steam, oil or other materials and its simple and robust structure allows it to be used reliably over long periods.

  • Electromagnetic Induction: the sensor does not use light.
  • Not affected by adhesion of dust, steam, oil or other materials.
  • Simple design and durable structure.
  • There are no consumable parts.
  • No changes in detection performance with time.
  • Truly maintenance free.

The NS-CPC sensor consists of a preamplifier and sensor (including 2 transmission coils, 2 reception coils and a specialized cable). The sensor straddles and is positioned facing the strip. The high- frequency magnetic field emitted from the transmission coils generates induced voltage in the receiving coils. This induced voltage changes with the strip position so the variances in the voltage at the receiving coils can be used to calculate the strip center position.
