Abstract

An apparatus for measuring a gap between a first mating surface of a first component and a second mating surface of a second component has a substrate. A plurality of capacitive sensors is coupled to the substrate. A controller is coupled to the plurality of capacitive sensors. The controller is used to select each individual capacitive sensor to measure the gap between the first mating surface of the first component and the second mating surface of the second component.
