Linear displacement transducers PTs 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. The core has to be in contact with the moving target object. One transducer of PTs series works with one chanel conditioner fe. WG06 amplifier. The PTs series is used to measure static and dynamic movement, thickness or bending of machines and constructions fe: microrobots, breath-analysers and so on.
