A transducer assembly includes a cap readily removable from a housing and enclosing a pressure transducer and a main valve body. Seals are located inside the housing which often are elastomeric or otherwise heat damageable. A top cartridge together with all of the seals inside the housing is readily disconnectable from the housing to separate the seals from the transducer assembly first end. This first end may then be heat sealed by soldering, brazing, or welding to a manifold or the like without any heat damage to the various seals. The transducer assembly then may be readily reassembled to form an operative transducer assembly. The foregoing Abstract is merely a resume of general applications, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
A transducer assembly having a first end thereof for assembly with a manifold or the like by heat sealing comprising:
A method of assembly of a transducer assembly first end with a manifold or the like by heat sealing, the transducer assembly including cartridge means in a transducer housing, said cartridge means including a main valve body and a pressure-to-electrical-signal transducer and each with sealing means to seal with said transducer housing, and a bore communicating from said transducer assembly first end through said main valve body with said transducer for applying pressure thereto,
