Linear Variable Differential Transformer. How LVDTs Work. The LVDT or Linear Variable Differential Transformer is a well established transducer design which has been used throughout many decades for the accurate measurement of displacement and within closed loops for the control of positioning.
Types of LVDTs. LD400:Miniature DC Output Displacement Transducers with Acetal Bearings Linear Position Sensors - determine whether you need to measure a relative current: C-in, AC-out, DC-in, DC-out; or measuring resonant frequencies of coils as a function of coil position, frequency based devices.
