Effectiveness of the Real Time Ferrograph and Other Oil Monitors as Related to Oil Filtration,

Abstract

A development model of an oil monitor known as the Real Time (R.T.) Ferrograph was evaluated on a bench tester to determine its effectiveness in detecting rolling contact fatigue or scoring type failures, especially as influenced by various levels of oil filtration. Comparisons of the R.T. Ferrograph are made with spectrometric oil analysis, a light scattering and attenuation device, an X-ray fluorescence device, a particle counter, and the analytical Ferrograph. Results of the testing showed the R.T. Ferrograph to be effective in detecting failures when the oil filtration level was above 40 micrometres. In addition, it correlates well with the other oil monitors at these filtration levels. Below the 40 micrometre oil filtration level the R.T. Ferrograph was found to be ineffective. (Author)
