LVDT (Linear Variable Differential Transformer), is an absolute position/displacement transducer that will convert a position or linear displacement from a mechanical reference (zero, or null position) into a proportional electrical signal containing phase (for direction) and amplitude (for distance) information. The LVDT operation does not require an electrical contact between the moving part (probe or core assembly) and the coil assembly to work, but instead relies on electromagnetic coupling; this and the fact that LVDTs can operate without any built-in electronic circuitry are the primary reasons why they have been widely used in applications where long life and high-reliability equipment under very severe environmental conditions as required, such as in Military/Aerospace, process controls, automation, robotics, nuclear, chemical plants, hydraulics, power turbines, and many others. LVDT’s come in two different ranges, either DC or AC output. DC versions, in general, have integral electronics or there is limited need for complex signal conditioning or AC variants which will require signal conditioning. There are lots of object application-based uses for an LVDT device, as they are not electromechanical there are many good uses for many devices.
