PSa Series AC/AC

Transformer linear displacement transducers (LVDT) of the PSa series, provided with a return spring, can to measure touching, without fixing of the core connecting rod. They can be used to measurements of: -displacement and change of dimensions or deflections of heavy, giant constructions, -wide changes of dilatation slits and a settlement irregularity of dam concrete blocks in hydroelectric plants. PRINCIPLE OF OPERATION The LVDT is a cylindrical electromechanical device consisting of one primary winding, two secondary windings and a moveable core . When the primary is powered and the core moved, the output from the secondaries is proportional to and in phase with the core movement. The construction gives a possibility to insert the core connecting rod from the any side of the transducer.
