Alternative Coding System Defining the Total and Severity of Wear

摘要

A ferrous debris monitor is described which is capable of measuring theconcentration of ferrous wear debris suspended in a lubricant and the severity of wear associated with particle size of this suspended debris. A coding system is proposed : PQ index(total wear):initial TDPQ slope(large particles):final TDPQ slope(small particles). Correlation with existing measurements is detailed.
