Abstract
Inductive and magnetic sensors employ variables and parameters like magnetic induction, magnetic flux, self-inductance, mutual inductance or magnetic resistance. By a particular construction of the device, these quantities are made dependent on an applied displacement or force. First we review various magnetic quantities and their relations. Next the operation and specifications of the major types of magnetic and inductive sensors are analysed, including Hall sensors, fluxgate sensors, eddy current sensors and magnetostrictive sensors. Special attention is given to transformer-type sensors (e.g. LVDT and resolvers). The chapter concludes with a section on applications, in which inductive and magnetic sensors are used to solve particular measurement problems.
