Defrosting a sensor in a vehicle system

摘要

Systems and methods for defrosting sensing components in fluid sensing system. In one embodiment, the invention provides a defrosting system that includes a sensing system. The sensing system includes a sensor operable to sense a characteristic of the fluid in a tank. The defrosting system includes a fluid pickup line spaced apart from the sensor, and a fluid return line. The fluid return line includes an output. The output is positioned to direct fluid onto the sensing system. In one embodiment, the defrosting system further comprises a pipe configured to provide the fluid to a system external to the tank. The fluid is heated by heat generated by the external system and directed onto the sensing system at least partially defrosts fluid contained within the sensing system.

1. A system for heating and sensing a fluid in a tank, the system comprising:
a focus tube configured to contain at least a portion of the fluid; a sensing system including a sensor operable to sense a characteristic of the fluid, the sensing system coupled to the focus tube; a fluid pickup line configured to take in fluid from the tank and spaced apart from the sensor; and a fluid return line configured to return the fluid to the tank, the fluid return line including an output, the output positioned to direct fluid onto the focus tube such that the fluid runs down the focus tube onto the sensing system and at least partially defrosts fluid contained within the sensing system.
