Title:
A pressure transmitting machine provided with a packed tube
Document Type and Number:
Japanese Patent JP6006426
Kind Code:
B2
Abstract:
A pressure transmitter has a pressure sensor, an isolator diaphragm, and a fill tube. Interior passages in the pressure sensor module body are filled with isolator fluid and provide fluid connections. The isolator fluid couples pressure from the first isolator diaphragm assembly to the pressure sensor. A first crimp portion of the fill tube radially narrows into a substantially solid circular cylindrical cross section to form a first primary seal that is resistant to high pressure cycling.
