An inductance-type, proximity-probe system for measurement of bearing film thicknesses and shaft orbits in high-temperature, liquid-sodium environment has been developed, built and tested. The probe system is designed to operate at temperatures up to 1200/sup 0/F and gap range of 0.004'' to 0.080'', with good linearity over about three-quarters of the range, when using probe pairs connected in push-pull. The probes were tested extensively in both gas and sodium environments, culminating in a 684 hours continuous test in a temperature range of 1050/sup 0/F to 1170/sup 0/F. The probes operated stably, repeatably and without undergoing performance changes.
