The output voltage of an eddy current displacement sensor (EC displacement sensor) depends on the heat treatment of the measuring object. The EC displacement sensor must detect a displacement of several tens of μm to allow the examination of the cha

A magnetoplated wire (MPW) is a copper wire whose circumference is plated with a magnetic thin film. The effects of using an MPW are a decrease in the proximity effect, an increase in inductance, and generation of more flux than when copper wire is u

Coil resistance is broken down into DC resistance, resistance due to the skin effect and resistance due to the proximity effect. Most of the coil resistance is composed of resistance due to the proximity effect in the high-frequency range. Thus, the
