Miniature displacement sensor

Abstract

Nd-Fe-B micromagnets and miniature Hall-effect sensors enable to build small measuring systems for micro-displacements. They can be applied as individual sensors, elements of sensor arrays or sources of position signals in miniature servodrives. A prototype miniature displacement transducer, with Hall-effect devices operating as a differential system, was elaborated and manufactured using 3D printing technology. A computer aided measurement system was launched allowing the prototype to be tested. The text presents the obtained basic metrological characteristics of the converter. Conclusions are drawn and future works are specified. It is possible to propose configuration ensuring a linear signal with resolution of at least 0.3 micrometer at a displacement range of 1 millimeter.
