High Resolution Position Inductive Transducers for Harsh Environmental Conditions

Abstract

In this paper the authors present certain theoretical, conceptual and technological aspects on main types of high resolution inductive transducers for harsh environmental conditions. Inductive resolvers, as well as inductive RVDT, have a priority in these applications, even other types of position transducers, as optical, capacitive or magnetic encoders are in competition. In the world there are many researchers that continue activity of conceptual and technological development to increase the resolution level of the inductive resolvers and inductive RVDT, as well as to obtain smaller and smaller dimensions, just it is requested in such kind of applications. On the other hand, the inductive transducers are more adapted at harsh mechanical and climatic conditions that are usual for special applications. The paper is referring, especially, to inductive transformers type resolver.
