We offer Linear Variable Differential Transformer useful for control labs. The present experimental unit comprises of a LVDT in a transparent box with lead screw based slow motion displacement, a mm scale for displacement measurement, and main unit consisting of excitation signal source, balanced demodulator, a 3.5 digit DVM and necessary power supplies. The signals are provided to the LVDT box through a cable from the main unit.
