Product description

PJx series, AC/AC 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. One transducer of PTx series works with a one channel conditioner like amplifier WG06. This  series is an intermediate version between small PTx and measuring large ranges PLx. It is used mainly to measure movement of concrete blocks in dams and  parts of devices in power plants.
