LVDT displacement sensors

LVDT stands for Linear Variable Differential Transformer (LVDT). The movable part of the LVDT is connected to a core rod. Inside the LVDT body, there is a primary coil (in the center) and two secondary coils (at both ends); the position of the core varies the induction into the two secondary coils. An external or internal electronics then converts this signal into a DC output that is proportional to the position of the core. Since the core does not touch the coils, there is no contact, resulting in an infinite resolution of the output.

LVDT displacement transducers are used in many different applications. The most common are in industrial production, where the need to know the position z.B. of a cutting tool is essential for the control system. Our displacement transducers have visited the depths of the oceans to measure valve positions and have been in space to measure the deflection in a mirror.You are equally at home in your factory or laboratory!
