Abstract
A new linear position transducer is disclosed which is substantially identical to the transducer described and illustrated in U.S. Pat. No. 4,667,158, except that the tubular layer contained between the coil and the outer shield comprises a silicon steel foil wrapped around the coil which has the effect of reducing the reluctance of this space to a low value. An electrical insulator is applied to one side of the silicon steel foil to prevent the creation of a current path between the coil and the outer shield of the transducer.
