Abstract: A fluid seal generally comprising a first fitting portion (50) and a second fitting portion (28), wherein at least one of the fitting portions can be deformed or deflected in a sealing relationship relative to the other fitting portion to form the fluid seal. A fitting includes a first fitting portion comprising a small projection (52) extending from a substantially planar surface. The fitting further includes a fitting portion comprising a substantially planar second surface (59). A fluid seal is created by forcing the small projection of the first fitting portion and substantially planar surface of the second fitting portion together. As they are forced together, the projection deforms to form the fluid seal. The fitting can be used to connect tubes, pipes, a valve, a manifold, and combinations thereof. The sealing method can also be used to protect the components of a pressure sensor from the corroding effects of process fluid vapors.

Abstract: A transmitter provides an output indicative of pressure of process fluid. The transmitter has a first body with a passageway filled with isolation fluid extending from a first port to a pressure sensor. A second body has an inlet for receiving process fluid and a second port. An isolation diaphragm between the first and second ports isolates process fluid from isolation fluid. A seal adjacent the diaphragm seals the diaphragm and couples the diaphragm to the second body. A spring urges the seal against the diaphragm.

Abstract: An improved apparatus for supporting a sensor housing on a surface to which vibrations are applied having mounts fixedly coupled to the surface and brackets fixedly coupled to the housing with a vibration isolation material supported between the mounts and the brackets to improve the vibration isolation to the housing by placing at least one half of the material of the apparatus in compression responsive to linear vibrations along at least two of the axes of the housing.
