Abstract
The sensor is of the type having a cylindrical body within which a measurement rod equipped with an outer measurement feeler bears a ferrite core which by its displacements influences the impedance of a system of coils to produce an electrical measurement signal. In the body, a fixed stop and an interposed movable stop make it possible to adjust the positioning of the measurement feeler in one or the other of two positions with respect to the electrical zero of the feeler and they have for this purpose interpenetration means with two stages spaced at an angle from each other and selected by manual push and rotation of the rod driving the movable stop in opposition to a spring and then release, in the manner of the so called 'bayonet' connections.
