Abstract
A status monitoring system includes a filter cap operatively connected to a filter housing having an inlet port and an outlet port. A magnet is affixed to the bottom side of the filter cap and extends down into the filter housing. A first thermistor is embedded in the magnet and physically isolated from the fluid for measuring the lagging temperature of the fluid due to the insulating effect of the filtered magnetite surrounding the magnet, while a second thermistor is placed inside the filter housing for measuring the temperature of the fluid. A difference between the measured temperatures, Δt, is then determined. When the Δt reaches a pre-determined point, the status monitoring system would send notification to its user and inform the user to perform the maintenance work on the magnetic filters.
