Abstract: For mechanical feedback servo actuator to test the zero output is unstable, the errors are existed between the measured amount of displacement and the length of actual measurement. The original traditional LVDT displacement sensor can not meet the demanding for high-accuracy test. The joints gap is eliminated when using the new displacement sensor with builtin return spring and the test reliability is improved at the same time.

Key words: Built-in, Return spring, Displacement sensor
