    Abstract: A flange mounted pressure transmitter uses a filled assembly having pressure transmitting fill fluid in a sealed capillary extending between a barrier diaphragm exposed to a fluid being monitored and a pressure sensor located in a housing attached to one end of a protective extension tube containing the capillary and supporting the diaphragm at the other end thereof. A gasket ring and a transmitter mounting flange are located on the exterior surface of the protecting tube and are arranged to provide a means for attaching the extension tube to a housing containing the fluid being monitored. The gasket ring is arranged to be welded to the exterior surface of the extension tube at a selectable distance from the barrier diaphragm which is effective to produce a desired location of the extension tube and the diaphragm within the housing containing the fluid being monitored.
