CONTACT POTENTIAL DIFFERENCE SENSOR TO MONITOR OIL PROPERTIES

摘要

A method and system (Fig. 1) for contact potential sensing of dielectric properties of a fluid. The method and system (Fig. 1) include a contact potential sensor (20,30), an open (Fig. 4 and 5) or closed loop for passing a fluid past the sensor, measuring a contact potential to characterize dielectric properties of the fluid and outputting the dielectric property information for analysis and response thereto.
