润滑油膜厚度的动态测试

A Study on the Pressure Instrument With Optical Fiber Microbcndor

本文论述了润滑油膜动态测试的有关问题.其中包括:电容传感器在油介质中的工作原理、测试精度分析、二次仪表设计、数据处理等.并且给出了测试系统及数据采集系统.

A new pressure measurement instrument with the passive diaphragm and the optical fiber microbendor is proposed in this paper. The techniques for stabilization of amplitude and modulation of the fiber coupled signal, ratio measurement of two fiber signals arc introduced. We discussed the improvement in stability, noise, drift, antiperturbation by means of taking these methods, and given the pressure beasurcment results.
