LVDT/LVIT

Precise Accurate Feed Back With High Volume Manufacturability

Linear Variable Differential Transducers LVDT

Linear-output devices showing displacement and magnitude from a zero reference position available in both long and short stroke types with ac-input/ac-output and dc-input/dc-output configurations.

These self generating transducers require no voltage input and provide high output linear velocity information. The physically linked actuator drives the magnet core through the coil producing a dc voltage output.

The LVDT is very flexible in its possible applications as a direct indication of displacement, in an alarm circuit or in a null balance servo system or in a complete instrumentation system providing the primary system input.
