Abstract
A displacement transducer for a valve in a housing includes a cylindrical displacement transducer core, a coil, a coil housing, and a compensation element. The coil is positioned in the coil housing, and radially encloses the core. The coil housing has a first side supported by the housing, and a supporting face positioned between the first side and an axial end side of the coil housing facing away from the valve such that a length change of the coil is not limited in an axial direction facing away from the valve. The housing is axially supported on the compensation element via the supporting face. A side of the compensation element facing away from the valve is supported on one or more of (i) an adjustable cover, (ii) a standard component of a supporting chain of the core, and (iii) a component formed from a material with a suitable coefficient of thermal expansion.
