Publication number: 20230194475Abstract: A system for detecting deposit formation on electrically-conductive materials in vapor and liquid phases includes a test cell for receiving a test liquid (e.g., 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 and at least a second set of electrical conductors in the vapor phase, each of the first and second sets of conductors including a live electrical conductor and a neutral electrical conductor. A power source supplies an electric current to each of the live electrical conductors. A sensor component detects an electrical property each of the sets of conductors, the electrical property changing in response to formation of an electrically-conductive deposit which connects the first and second conductors in a respective set of conductors. Preferably, the electrical properties are detected by magnetic sensors, such as Hall effect sensors or eddy current sensors.Type: ApplicationFiled: May 28, 2021Publication date: June 22, 2023Applicant: The Lubrizol CorporationInventors: Mitchell Andrew Peplow, Gregory James Hunt, Christopher Paul Prengaman, Rahmeen Fatima Javaid
