摘要：A differential transformer magnetic permeability sensor includes a substrate, adrive coil, a first differential coil, a second differential coil, a first interconnection pattern,and a second interconnection pattern. The first differential coil is disposed at a side of a

first surface of the substrate, and an induced voltage is generated therein when the drivecoil is driven. The second differential coil is disposed at a side of a second surface of thesubstrate, and an induced voltage is generated therein when the drive coil is driven. Thefirst interconnection pattern is located on the first surface and allows the first differentialcoil to serve as a reference coil, and the second differential coil as a sensing coil. Thesecond interconnection pattern is located on the second surface and allows the seconddifferential coil to serve as a reference coil, and the first differential coil as a sensing coil.
