Conductive Cable, Wire and Tube Testing Solutions for Process Control

Higher Thin-film and substrate quality through fast and precise Inline Measurement
based on non-contact eddy current technology.

Introduction

The EddyCus® Inline RS series is an annular sensor engineered for non-contact, continuous inline testing of any conductive material passing through a tube or shaped as a wire. The sensor features a standard opening diameter of 20 mm, with custom sizes up to 100 mm available on request. This solution supports advanced process control, yield optimization, and reliable inspection of incoming and outgoing goods.

The device is typically used for:

  • Conductive coatings on non-conductive materials (conductive coated glass fiber, coated threads)
  • Conductive wires (metal filaments and wires, metal fibers)
  • Conductive band (steal bands, susceptors)
  • Electrical cords and wires
  • Conductive pastes and slurrys
  • Other conductive materials (carbon fiber materials such as roving or rods)

Supported Substrates

Wafer, Glass, etc. with 150 / 200 / 300 mm diameter

    • Particle size, volume fraction, viscosity, morphology
  • Slurry characteristics affect on downstream processes
    • Coating (thickness, layer density)
      • Spatial distribution of active material in through-plane direction
    • Drying behavior (diffusion paths, porosity)
    • Calendering behavior
    • Post-Calendering drying
    • Filling with Electrolyte
