Ferrous Wear Concentration

Measures the amount of ferrous wear in a lubricant.


Operating Principle. A wear particle analyzer quantifies the amount of ferrous material present in a sample of fluid. A measured amount of sample is inserted into the analyzer and amount of ferrous material is determined by change in magnetic flux. This change is then converted into ferrous concentration in parts per million. Instead of using a light sensor to measure particles and report a unitless number, this instrument measures concentration and reports the results in parts per million. Using this method, there are no interferences with non-ferrous particles.

Significance. This test gives a direct measure of the amount of ferrous wear metals present in a sample. Trending of ferrous concentration reveals changes in the wear mode of the system.

Advantages. Excellent trending device for “dirty” systems such as large splash lubricated gearboxes. No particle size limitation.

Disadvantages. Does not detect non-ferrous particles.

Application. Gearboxes, Anti-Friction bearings.
