Abstract
The measurement device for generating a measurement signal from an object without physical contact with the object includes a magnetizable plastic coil body and at least one coil arranged on the coil body and through which a current flows during generation of the measurement signal. The coil body can be part of a one-piece injection molded plastic part consisting of a magnetizable plastic material. In a preferred embodiment the one-piece injection molded magnetizable plastic part consists of ring-like mounting element and a sleeve-like extension with a exterior circumferential groove for the coil or coils which acts as the magnetizable plastic coil body. The magnetizable plastic substance can be a polyamide plastic substance filled with a weakly magnetizable material such as an iron-cobalt powder.
