Linear variable differential transformer
open-in-new
<p>The linear variable differential transformer (LVDT) – also called linear variable displacement transformer, linear variable displacement transducer, or simply differential transformer – is a type of electrical <a href="/facts/Transformer/EYYfXWrF">transformer</a> used for measuring <a href="/facts/Linear_displacement/Vom0QwWe">linear displacement</a> (position along a given direction). It is the base of LVDT-type <a href="/facts/Displacement_sensor/3gP9jAVz">displacement sensors</a>. A counterpart to this device that is used for measuring <a href="/facts/Rotary_displacement/qoqvM9Np">rotary displacement</a> is called a <i><a href="/facts/Rotary_variable_differential_transformer/Hk9ReS00">rotary variable differential transformer</a></i> (RVDT). </p>
