Linear variable differential transformers (LVDT) are electrical transformer sensors to measure linear displacement. Driven by an AC excitation source, the LVDT generates a pair of AC output signals modulated according to the core's mechanical position (displacement). LVDTs have been widely used in applications such as power turbines, hydraulics, automation, aircraft, satellites, nuclear reactors, and many others. These transducers have low hysteresis and excellent repeatability.

Linear Variable Differential Transformer (LVDT) and Rotary Variable Differential Transformer (RVDT) are transformer-type voltage/current transducers that convert a linear/rotary movement of a core/shaft to a multi-wire differential AC electrical signal. Both deliver signals linearly proportional to the position of a shaft (magnetic induction core). An LVDT/RVDT simulator is used to convert digital positional commands to corresponding AC signals.
