The lubricating gap of a plain bearing is influenced by several factors such as temperature, speed, angle, load etc. This influence can only be measured under operating conditions.
Therefore, a measurement system which detects the gap size or the shaft displacement is subject to strict requirements: temperature stability, resistance to pressure, oil resistance, small size.
eddyNCDT systems with the miniature sensors U 05 and S 05 have been used successfully for displacement measurements in the crankshaft bearing of internal combustion engines. The special design of these minia- ture sensors enables them to be inserted in even the smallest of bearings where they deliver reliable, accurate measuring results and high resolution of the values.
