PVEH, Inductive Transducer (LVDT – Linear Variable Differential Transformer)
When the main spool is moved a voltage is induced proportional to the spool position. The use of LVDT
gives contact-free (proximity) registration of the main spool position. This means an extra-long working
life and no limitation as regards the type of hydraulic fluid used. In addition, LVDT gives a precise position
signal of high resolution.
