PJy series, DC/DC group, like other displacement transducers made by Peltron are based on the differential transformer principle – LVDT.  The transformer is placed inside a cylindrical case. There is a magnetic core inside the transformer. Displacement of the core results in a change in the transducer’s output signal.  This series is not equipped with a return spring so the core’s end has to be fixed to a moveable object. To work properly each transducer of  PJy series needs only power supply. These transducers are used to measure static linear displacement also to changes of length and thickness of materials, bending of machines and constructions./>)
