  • Machine fluid pressure indication system
    Patent number: 6678607
    Abstract: A system, method and apparatus are disclosed for creating a signal that indicates the pressure of the fluid in an engine. A switch or sensor determines whether the actual pressure is greater or less than a threshold pressure. If the actual pressure is less than the threshold pressure, a sensed pressure (e.g., the output of a pressure sensor) is used. If the sensed pressure is greater than the threshold pressure, then the output is derived from an estimate of the fluid pressure, where the estimate is based on other operating parameters of the engine. The output signal can be used as an input to a display visible by an operator, controller logs, diagnostic systems, and the like.
