- An eddy current probes is supported against the force of gravity with an air bearing while being urged horizontally toward the specimen being examined by a spring and displaced horizontally against the force of the spring pneumatically. The pneumatic displacement is accomplished by flowing air between a plenum chamber fixed with respect to the probe and the surface of the specimen. In this way, the surface of the specimens can be examined without making mechanical contact therewith while precisely controlling the distance at which the probe stands-off from the surface of the specimen. 4 figs.
