An LVDT is used to measure distance along a straight path. Unlike a linear optical encoder, this method uses measurements of inductance between two electrical coils to judge the distance.

Linear Variable Differential Transformer (LVDT) sensors are inductive type devices that measure linear displacement. These sensors consist of three coils—a primary and two 180° out-of-phase ...

Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic ...

On these models, the movable arm is pivoted, one end is the knife edge and the other is connected to an armature that moves through an LVDT coil. A majority of these extensometers can be adapted to ...
