The modified system is shown in the figure below where a resistance ratio element is used. How LVDTs Work – The LVDT Working Principle. "The output signal does not depend on the size of the sensor, and this is a particular advantage", says Thomas Kleckers. The resistive transducer element works on the principle that the resistance of the element is directly proportional to the length of the conductor and inversely proportional to the area of the conductor.
