Oil Performance Monitor
- Oil Performance Monitor: Control Unit ...
Monitoring the deterioration of lubricants gains more and more relevance with regard to design of gearing and internal combustion engines as well as in operation of those aggregates. All this in terms of ecological and economical aspects and of parameters as reliability, failure probability and the length of oil change periods.
Novel fuels as biodiesel or ethanol cause greater effect to lubricants used in combustion engines than fuels based on mineral oil. For instance, the fuel entry to the lubricant is significantly higher when using biodiesel, compared to mineral oil diesel.
Important criteria for lubricant deterioration are particle entry, thermal oxidation, chemical conversion and mechanical destruction of high-molecular additives.

Essential quantifiable symptoms of oil deterioration are viscosity alteration, an increase of insoluble contamination (including metallic content) and an alteration of neutralisation ability (Total Base Number "TBN" and Total Acid Number "TAN").
The oil performance monitor simultaneously and contiuously measures the values which repesent these symptoms: the viscosity, the specific electrical conductivity and the relative dielectric coefficient. The measurement is non-reactive and non-destructive.
