摘要
A method and apparatus for determining the total base number of a used lubricant from an open, all loss, lubricating system. An AC voltage signal is applied between electrodes immersed in the used lubricant and a used-lubricant dependent response to the applied signal measured. The used lubricant base number is determined from the response. To allow for changes in the fresh lubricant inputted to the open lubricating system, the method and apparatus can have means for determining properties of the fresh lubricant needed to determine the total base number of used lubricant. To allow for possible contamination of the used lubricant, the method and apparatus can have means for determining the concentration of contamination and for determining properties of the contaminant needed to determine the total base number of used lubricant.
