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.
The main advantage of the LVDT transducer over other types of displacement transducer is the high degree of robustness. Because there is no physical contact across the sensing element, there is no wear in the sensing element. Because the device relies on the coupling of magnetic flux, an LVDT can have infinite resolution.
