A Linear Variable Differential Transformer (LVDT) is an electromechanical device used to measure linear displacement. It operates on the principle of electromagnetic induction, where a movable core within a coil assembly alters the output voltage in response to its position. This allows for precise measurement of linear movement, making LVDTs popular in various applications, including industrial automation and aerospace. LVDTs are known for their high accuracy, reliability, and ability to operate in harsh environments. They typically consist of three coils: a primary coil and two secondary coils. The differential output from the secondary coils provides a direct measurement of the core's position, ensuring consistent performance across a wide range of conditions.
