The Intelligent Design of Fiber-optical Measurement System for Lubricant Film Thickness

Based on the study on the measuring technology of the lubricant film using a fiber-optical displacement sensor, an on-line integrated intelligent measurement system was set up, and the related experiment was done for checking the performances of the system. The result shows that the measurement system is practicable and sensitive, and its measurement effect is very good. The signal sampling board and its following communication system developed run promptly and accurately, and the data processing software and the virtual instrument system developed have some good performances, which are stable and convenience. According to these advantages described above, the measuring system can be successfully applied in the state measurement of the lubrication film thickness, and it has intelligent feature obviously.
