- Abstract:
- The Linear Variable Differential Transformer (LVDT) is an inductive sensor which is used to measure linear displacement and finds uses in modern machine-tool, robotics, avionics, and computerized manufacturing. Its basic structure consists of a primary coil and two secondary coils like an electrical transformer. However, LVDT has a movable magnetic core that when the primary coil is excited with an AC voltage source, induced secondary voltages vary with the displacement of the core. In general, this accurate and reliable displacement-to-electrical sensor can be modeled in two forms: geometrical-parameter-based model and electrical-parameterbased model. Both are very used. However, research results based in geometricalbased model may become useless when only parameters from electrical one are known. In this paper, it is shown a way of conversion from geometrical- to electricalbased model in order to allow the interaction from one to other.
