Abstract
A system for detecting deposit formation on electrically-conductive materials in liquid and vapor phases includes a test cell for receiving a test liquid, for example. a lubricant, A heater heats the test liquid to generate a vapor phase of the test liquid in the test cell. A support frame supports at least a first set of electrical conductors in the test liquid, liquid phase, and at least a second set of electrical conductors in the vapor phase, each including a live and a neutral electrical conductor. A power source supplies electric current to the live electrical conductors. A sensor detects an electrical property in each set of conductors, which changes in response to formation of an electrically-conductive deposit connecting the first and second conductors in a respective set of conductors. Preferably, the electrical properties are detected by magnetic sensors such as Hall effect or eddy current sensors.
