Claim:
1. A fluid filtration system, comprising: a filter manifold defining a fluid inlet and a fluid outlet; a valve in upstream fluid communication with the filter manifold to control the flow of fluid thereto; a filter cartridge attached to the filter manifold, the filter cartridge having a filter housing defining a chamber, the filter cartridge defining an outlet for directing the flow of fluid out of the filter cartridge; a filter element received into the chamber of the filter housing upstream from the filter outlet; a first temperature sensor configured to detect the temperature of the filter cartridge, the first temperature sensor being embedded in the filter housing; a second temperature sensor for measuring the temperature of fluid passing through the filter outlet, the second temperature sensor being positioned downstream from the chamber of the filter housing and upstream from the fluid outlet of the filter manifold; and at least one controller in communication with the first temperature sensor, the second temperature sensor, and the valve through one or more leads, wherein the controller is configured to receive temperature measurements through the one or more leads from the first temperature sensor and the second temperature sensor when a fluid is flowed the filter cartridge, predict a filter cartridge leak based on the temperature measurements over time, and execute one or more corrective actions when a leak is predicted, the one or more corrective actions including signaling the valve to stop a flow of fluid through the filter manifold.
