Abstract
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.
