摘要： An apparatus measures relative displacement between a first end and a second end of a shaft. The first and second ends being centered on a shaft axis. The apparatus includes first and second ferromagnetic plates. The first ferromagnetic plate has a first side and a second side and is connected to the first end. The first ferromagnetic plate is centered on the shaft axis and has a plurality of ferromagnetic teeth extending from the first side and in a first direction parallel to the shaft. The second ferromagnetic plate has a first side and a second side and is connected to the second end. The second ferromagnetic plate is centered on the shaft axis. The first and second ferromagnetic plates form a gap. The apparatus further includes a plurality of magnets having a magnetic field and a sensing device. The magnets are coupled to the first side of the second ferromagnetic plate. The sensing device is disposed within the gap for sensing a magnetic flux of the magnetic field.

摘要： An apparatus for measuring relative displacement between a first shaft and a second shaft includes first and second rotor assemblies. The first rotor assembly is coupled to the first shaft and is centered on an axis. The second rotor assembly is coupled to the second shaft. The second rotor assembly has first and second stator plates. Each of the first and second stator plates includes an upper surface and a lower surface. The upper and lower surfaces are parallel. The first and second stator plates include a plurality of teeth extending in a direction radial of the axis. The first and second stator plates form a gap between the lower surface of the first stator plate and the upper surface of the second stator plate. The apparatus further includes at least one magnet having a magnetic field and disposed on the first rotor assembly and a sensing device disposed within the gap for sensing a magnetic flux of the magnetic field.
