ABSTRACT:
A monitoring system for testing the integrity of seal structures, filled with an electrically non-conductive fluid and for validating measurements of a measurement device. The monitoring system includes electrodes disposed in the fluid for measuring an electrical property of the fluid. The system indicates when the measured electrical property changes, which indicates contamination of the fluid.
