Pressure sensor system with integrated thermal stabilization and method of using |
摘要 |
The present invention relates to a method of determining both pressures and temperatures in a high temperature environment. The present invention also relates to a method of determining temperatures about a pressure-sensing element using a bi-functional heater. In addition, the present invention preferably relates to a pressure sensor with the pressure-sensing element and a heating element both integrated into the sensor's packaging, preferably onto the diaphragm of the pressure sensor, and particularly to such a pressure sensor capable of operating at high or elevated temperatures, and even more particularly to such a pressure sensor wherein the heating element is capable of both heating, at least in part, the pressure-sensing element and monitoring the temperature of the application area. Preferably, the pressure-sensing element is formed from shape memory alloy (SMA) materials that can be used at high or elevated temperatures as a pressure sensor with high sensitivity. |

1. A method of adjusting an engine comprising steps of:
providing a pressure-sensing element for a pressure chamber in which a pressure is to be measured or estimated; providing a heating element in or about the pressure sensing element used to measure the pressure; heating the pressure-sensing element, at least in part, with the heating element; measuring or estimating the pressure of the pressure chamber through the pressure-sensing element; and adjusting parameters of combustion for the pressure chamber based at least in part on the measured or estimated pressure. |
