Patent ID: 7137301

Claim:
A method for establishing a reference pressure within a reference chamber of a capacitive pressure transducer assembly, the method comprising: providing a pressure transducer assembly having an aperture; providing an aperture cover; depositing a sealing material on at least one of a sealing area that surrounds the aperture and a sealing area of the aperture cover; positioning the aperture cover in a space that is defined by a guide; coupling the guide to a portion of the transducer assembly that is adjacent to the aperture; placing the pressure transducer assembly, the aperture cover and the guide in a pressure chamber of a housing, the aperture providing a fluid pathway between the reference chamber of the pressure transducer assembly and the pressure chamber of the housing; generating a pressure in the pressure chamber; rotating the transducer assembly and the guide so that gravity moves the aperture cover towards the aperture; melting the sealing material; and allowing the sealing material to cool.
