A compressed air supply system for motor vehicles includes a compressor, control electronics, an air dryer having an inlet channel for non-dried compressed air, an outlet channel for the dried compressed air, and a dehumidification device through which the compressed air to be dried can flow, a pressure regulator having an outlet valve for controlling the compressor between an idle phase and a load phase, a multi-circuit safety valve that is connected to the outlet channel of the air dryer via a compressed air line, and over-flow valves for the individual circuits, a regeneration valve and a moisture sensor for detecting the atmospheric moisture in the compressed air flowing in the compressed air line. To reduce the detrimental effects of admixtures and components of the compressed air on the moisture sensor, the moisture sensor is located in a bypass channel of the compressed air line.

An improved inductive displacement sensor for use in a hydraulic accumulator for sampling the degree of filling of the hydraulic accumulator. The displacement sensor is provided with an electrical winding on a coil former. To reduce the gas volume of the hydraulic accumulator, the winding space not occupied by the electrical winding in the coil former is filled with a further winding formed from plastic or other non-magnetic material. The further winding is not electrically connected and is wound about the electrical winding.

An angle-of-rotation sensor comprises a coil, a magnetically conductive element within the coil which is rotatable around an axis of rotation, the axis of rotation of the magnetically conductive element being at least partially within the coil, and a single winding for the coil. The angle-of-rotation of the magnetically conductive element is determined by measuring the change in self-inductance in the coil when the magnetically conductive element is caused to rotate.
