What Is an LVDT Sensor? Working Principle, Types, and Applications in Precision Gauging

LVDT stands for Linear Variable Differential Transformer. Strip away the jargon and it’s simply a device that converts a small linear movement, sometimes as tiny as a few microns, into an electrical signal that a display or controller can read. Because it does this without any physical contact between moving parts that would cause friction or wear, it holds up to millions of measurement cycles without losing accuracy.In everyday shop-floor language, people often call it an LVDT probe when…
