專利摘要 A high-temperature gas pressure measuring method includes a pressure measuring gas housing dividing step for dividing a pressure measuring gas housing into a pressure measuring room and a pressure referring room by a metal diaphragm; a gas introducing step for introducing high temperature gas into the pressure measuring room and introducing a reference pressure gas into the pressure referring room; a displacement measuring step for measuring a displacement of the metal diaphragm, wherein the displacement is caused by pressure difference between the two rooms in pressure measuring gas housing; and a pressure determining step for measuring the pressure of a high-temperature and/or corrosive to-measure pressure gas. The method dispenses with any corrosion-resistant and heat-resistant pressure sensing component and thus cuts costs.
