Abstract
A surface measurement apparatus of the type in which a sensor is traversed along a path in contact with or adjacent the surface of a component under test. The sensor has three or more transducers which, in the described embodiment, physically contact the surface under test and produce individual signals as they are traversed along the same path over the surface of the component under test. The signals produced by the transducers are amplified and combined in such a way that the composite signal so produced is not dependent on any variation in the position of the body of the transducers as the device is traversed along the surface of the component under test thereby allowing the use of sensors which are not mounted on accurately preformed datum-determining mounts such as a flat bed or an accurate spindle.
