    • The novel inclined plate 360 degree absolute angle sensor is designed to measure the absolute angle created by a base and a rotating surface. The assembly contains a metal inclined plate positioned above four coils so that coils one and two are at the minimum and maximum distance from the plate respectively, while at the same time, coils three and four are equidistant from the inclined plate. Rotation of the plate around a centerline, changes the distance that all four coils with respect to the inclined plate which, in turn, creates a change of the inductance of the coils. This change in inductance may be measured with alternating current bridge technologies in order to provide a measure of absolute angular position of a rotating surface with respect to the base.
    • 新型倾斜板360度绝对角度传感器设计用于测量由基座和旋转表面产生的绝对角度。 该组件包含位于四个线圈之上的金属倾斜板,使得线圈1和2分别处于距离板的最小和最大距离,而同时,线圈3和4与倾斜板等距。 围绕中心线旋转板,改变所有四个线圈相对于倾斜板的距离,这反过来又产生线圈的电感的变化。 可以用交流电桥技术测量电感的这种变化,以便提供旋转表面相对于基座的绝对角位置的量度。
