Design of inductive shift transducers
Abstract
Plunger type inductive transducers detecting shifts are simple in design, show good metrological indicators, and consist essentially of an induction coil and a ferromagnetic core. The design problem is to increase sensitivity and to reduce error. However, the determination of operating characteristics on the basis of electromagnetic circuit theory is difficult and leads to many errors. Consequently, an experimental set up was made which consisted of a measurement generator constraining the transducer coil, a micrometer screw and a frequency meter. It was used to establish relations for operational parameters which make it possible to design a transducer of the required size with the necessary sensitivities and error limits and to specify the required design parameters.
