First Claim
Patent Images
1. A system that facilitates in situ determination of lubricity in a fluid, comprising:
- a multi-element sensor positioned within a machine, the multi-element sensor obtains data regarding a plurality of parameters of a fluid, the multi-element sensor comprising two surfaces, at least one of the surfaces comprises a layer of material that wears readily;
a component that measures capacitance resulting from wear of the material; and
a component that calculates lubricity of the fluid based at least in part upon the measured parameters.

13. A method for in situ determination of lubricity in a fluid within machinery, comprising:
-
placing two surfaces together with fluid between the two surfaces; moving one surface to generate a frictional force by relative movement between the two surfaces and the fluid; and calculating the force required to prevent the other surface from moving relatively and using the information for lubricity measurement. - View Dependent Claims (14, 15, 16)

17. A system for calculating lubricity of a fluid, comprising:
-
means for exerting a force on at least two surfaces to create a friction force between the two surfaces; means for maintaining fluid between the two surfaces; means for monitoring the force exerted on the surfaces; and means for calculating the lubricity of the fluid from the forces. - View Dependent Claims (18)
