Stress Distribution on the Fe Based Amorphous Toroidal Transducer Core

[摘要] The basic principles of sensors are the transmission of energy from one system to another. In general, an electrical signal is produced by the change of a physical property induced by the applied change of a second parameter. In the case of magnetic transducers either the property or the parameter would have a magnetic context. For example, in magnetoelastic toroidal transducers, the induced changes of a physical property, that is, the variation of permeability caused by the applied external force are used to produce a variation in output signal. The linearity, magnitude, sensitivity, and repeatability of the relationship between the output signal of the transducer and the physical property define the quality of the transducer.
