Abstract

One of the displacement measurement methods is using inductive sensors, usable for both small and large displacement. In this paper a 3-D linear inductive displacement sensor has been introduced. The proposed sensor consists of 2 elements that can measure 5cm with accuracy of 100ìm in large scale measurement. The first part is a coil and the second is a movable core that moves within the coil and it operate like differential pair. For transforming the value of varying in inductance that is in the result of approaching the target to the sensor, inductance varying is transformed to the voltage varying in vet son bridge circuit and finally, the value of displacement can be obtain.
