Abstract

An inductive measuring transducer impermeable to pressure media for use with a fluidic adjusting member such as a multiple position valve as a receiving casing of non magnetic working material for receiving a magnetic core, coils surrounding the casing which are, in turn, surrounded by a housing. An operating rod passes into the casing through a connecting member and operates the core. The casing is formed as continuous, hollow cylindrical tube with a closing member or plug inserted in one end and attached in fluid tight relationship. The other end of the receiving casing is tightly connected with the connecting member which is formed as a separate part from the receiving casing.
