Abstract
A system for determining a health status of a tank is provided. The system includes a temperature sensor, a pressure sensor, a sensor coupled to a hydraulic actuator, a breather valve, and a controller. The controller is configured to receive a signal indicative of a temperature and a volume of a fluid within the tank from the temperature sensor and the sensor coupled to the hydraulic actuator respectively. The controller is configured to determine an estimated pressure of the fluid within the tank based on the received signals and a breather performance curve. The controller is configured to receive a signal indicative of a pressure of the fluid within the tank and compare it with the estimated pressure. The controller is also configured to determine the health status of the tank and to actuate one or more of an operator console display unit and the hydraulic actuator.
