LVDTs for Linear Displacement Measurements

LVDT stands for Linear Variable Differential Transformer. The basic unit consists of a primary coil and two secondary coils wound on a coil form.  A ferromagnetic core links the electromagnetic field of the primary coil to the secondary coils. Differencing the output of these coils will result in a voltage proportional to the relative movement of the core versus the coils.
