Linear displacement transducers PTz series, DC/DC group, like other displacement transducers made by Peltron are based on the differential transformer principle – LVDT. The transformer and electronic board (generator and demodulator) are 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 fixed to the moving target object. PTz transducers do not need any additional devices to work only power supply. The PTz series is used to measure static and dynamic movement, thickness or bending of small machines and constructions fe: microrobots, breath-analysers and so on.
