Cutaway view of an LVDT. Current is driven through the primary coil at , causing an induction current to be generated through the secondary coils at . The linear variable differential transformer (LVDT) – also called linear variable displacement transformer, [1] linear variable displacement transducer, [2] or simply differential transformer[3] – is a type of electrical transformer [4] used ...
An LVDT provides reliable position measurement for applications that include aerospace, industrial automation, subsea, power generation, and test and measurement.
The LVDT stands for Linear Variable Differential Transformer. It converts the Linear motion into an electrical signal using an inductive transducer. Due to its superior sensitivity and accuracy over other inductive transducers, the LVDT is extensively used in many different fields. For measuring linear distance, the linear variable differential transformer (LVDT) is a precise and trustworthy ...
The linear variable differential transformer (LVDT) is an accurate and reliable method for measuring linear distance. LVDTs find uses in modern machine-tools, robotics, avionics, and computerized manufacturing. As shown in Figure 1, the LVDT is a position-to-electrical sensor whose output is proportional to the position of a movable magnetic core. The core moves linearly inside a transformer ...
An LVDT (Linear Variable Differential Transformer) is an electromechanical transducer that converts object into a corresponding electrical signal. Submicron motions are resolvable. Many phenomena produce, or can be used to produce, length changes which in turn can be measured and converted into a measurement of the phenomenon (e.g., pressure, temperature). The commercial LVDT ...
LVDT s provide an extremely reliable solution for a precise linear differential (position) and gauging measurement. Linear variable differential transformer can be used wherever a physical displacement or position needs to be converted into an electrical signal for indication or control purposes.
