A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement.

Digital LVDT sensor ZET 7111-L
-
ZET 7111-L is a digital LVDT displacement sensor. It requires no special adjustment and starts measuring right after power is on.

PXI/PXIe LVDT, RVDT, Resolver Simulator Modules
-
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.
