A.3.3 Engineered solutions
When standard model codes are not sufficient to fulfill requirements, please consult the factory
to explore possible Engineered Solutions. This is typically, but not exclusively, related to the
choice of wetted materials or the design of a process connection. These Engineered Solutions
are part of the expanded offerings and may be subject to additional delivery lead time. For
ordering, factory will supply a special R-labeled numeric option code that should be added at
the end of the standard model string. See example model string below.
Example Model String: 5402-A-H-1-E5-45-PV-CA-M1C1-R1234
A.3.4 Tank connection and antennas
Tank connection
The tank connection consists of a tank seal, a flange, Tri-Clamp™, or NPT thread.
Certain models of tank connections have a tank connection design with a protective plate of the
same material as the antenna. This is to prevent the 316L / EN1.4404 stainless steel flange from
being exposed to the tank atmosphere. See “Dimensional drawings and mechanical properties”
on page 200.
Flange dimensions
Follows ASME B16.5, JIS B2220, and EN 1092-1 standards. For more information, see “Standard
flanges” on page 205.
Antennas
Cone, Process Seal, and Rod Antenna. Cone antennas can be ordered in different materials.
Extended cone antennas are available in SST 316L.
