What is full form of lvdt why it is called transformer?

The full form of LVDT is Linear Variable Differential Transformer. It is called a transformer because it operates on the principle of electromagnetic induction, similar to electrical Transformers, to convert linear displacement into an electrical signal. The LVDT consists of a primary coil and two secondary coils, which produce a differential output voltage proportional to the position of a movable core within the coils. This design allows it to provide accurate and precise measurements of linear motion.
