AN ON-LINE DEVICE FOR MEASURING QUANTITATIVE PARTICLE CONTAMINATION IN LUBRICATING OILS

摘要

The present invention is intended to measure the degree of contamination in a lubricating oil using the fact that the intensity of transmitted light differs depending on the amount of the contaminated particles when the light passes through the lubricating oil. A first optical fiber for transmitting the projected light, a first optical lens for introducing the light transmitted through the first optical fiber into the lubricating oil sample as parallel light, and a second optical lens for collecting the light transmitted through the lubricating oil sample A photodiode sensing light transmitted through the second optical fiber, and a magnetic field applied to the lubricant sample to measure the relative proportions of the magnetic and non-magnetic contaminant particles in the lubricant sample For example. In addition, we can analyze and store the measured data using a computer, connect the computer and the communication network, and enable data transmission.
