Abstract
This study proposes the development of contamination measurement for industrial machines based on magnetic field method. A permanent magnet was used to generate the 0.17 T magnetic fields and Hall Effect sensor was applied to measure the contamination level of metal particles in industrial machine lubricant during operation time and to predict the replacement period if the lubricant condition does not meet the standard (NAS 1638). Contamination level of metal particles was directly related to the output voltage of Hall Effect sensor. When there was any movement of metal particles to the permanent magnet, the measured result was then transferred to a computer for analysis. This methodology could be applied to experiment the conditions of used lubricant for assessing the contamination and the metal particle remaining in the tank or inside the pipe of the machine as well as the conditions of car lubricant and other lubricants used in industrial processes.
Highlights
The conditions of lubricant are vital for industrial machine efficiency as they are related to machine damage caused by lubricant deterioration
This study is an alternative measurement by using magnetic field together with Hall Effect sensor which can be applied for examining the lubricant contamination of metal particles based on NAS 1638 standard with high accuracy and reliability
For NAS 14 downward, insignificant variation of output voltage from Hall Effect sensor was observed or this system cannot distinguish the contamination of metal particles lower than NAS 14
Summary
The conditions of lubricant are vital for industrial machine efficiency as they are related to machine damage caused by lubricant deterioration. The lubricant for each type of machine should be used in specific period. The lubricant conditions would be gradually deteriorated earlier than expected due to metal particles cased by machine wear itself or exterior contamination and the maintenance period would not be appropriate for a given machine. This study is an alternative measurement by using magnetic field together with Hall Effect sensor which can be applied for examining the lubricant contamination of metal particles based on NAS 1638 standard with high accuracy and reliability
