Abstract

The paper describes an inductive magnetic transducer for on-line recording of translations and vibrations. The transducer consists of an iron cored sensor coil and simple accompanying circuitry. The main features which are peculiar to the present transducer are (a) facility for linearizing the voltage versus displacement characteristic for certain regions of distances, (b) ability to measure vibrations and translations of both ferromagnetic objects and nonferromagnetic conductive objects, (c) relative simplicity of circuitry, and (d) the fact that only passive components are used for the transducer and an output voltage enhancement is attained by the employment of resonance. The paper is introduced by a comprehensive review of various types of magnetic transducers.

摘要

本文描述了一种用于在线记录平移和振动的感应磁传感器。该传感器由一个铁芯感应线圈和简单的附属电路组成。这种传感器特有的主要特性有：（a）在一定距离区域内使电压与位移特性线性化的能力；（b）能够测量铁磁物体和非铁磁导电物体的振动和平移；（c）电路相对简单；（d）该传感器仅使用无源元件，并且通过采用谐振来提高输出电压。本文开篇对各类磁传感器进行了全面综述。
