文档介绍：Fundamentals of Measurement Technology (9) Prof. Wang Boxiong Inductive transducers are based on the voltage output of an inductor (or coil) whose inductance changes in response to changes in the measurand. A classification of inductive transducers : Variable self-inductance Single coil (simple variable permeance) Two coil (or single coil with center tap) connected for inductance ratio Variable mutual inductance Simple two coil Three coil (using series opposition) Variable reluctance Moving iron Moving coil Moving Inductive transducers Simple permeance-varying Self-inductance arrangements Self-inductance arrangements Fig. Principle of permeance-varying transducer 1-coil 2-core 3-armature Self-inductance arrangements
