Abstract

Inductive sensors have been widely used for precise measurement of position, displacement, temperature and pressure as they are extremely reliable in the harsh industrial atmosphere. In this paper, fractional order models of inductive transducers namely fractional order variable reluctance inductive transducer and fractional order resonant inductive transducer are developed and its characteristics are analysed. The impact of fractional order parameter on the characteristics like sensitivity and nonlinearity of the fractional order transducer are studied. The results are enriched when a fractional order inductor is connected in parallel to the fractional order resonant inductive transducer.
