The LVDT is an electromechanical device that provides an output voltage which is proportional to the
displacement of a moveable core extension. The core extension is mounted inside the hollow piston rod and
moves as the piston rod moves. The LVDT coil is secured to the pedestal base by a locking collar. The core
extension is positioned in the LVDT coil to provide a zero reference point, and is locked in place with a locking
setscrew.
As the piston rod moves during operation, the output voltage from the LVDT indicates how far the piston rod
has moved from the zero reference point.
