Differential Transformer

A type of electrical transformer used to measure linear displacement or position. Differential transformers are electromechanical sensors that produce a linear electrical output directly proportional to the position of a movable ferrous core of a nickel-iron alloy. Typically, the differential transformer body is fixed in place and the ferrous core is attached to the moving element on the piece of equipment for position feedback.

Also known as a Linear Variable Differential Transformer.
