The tank connection consists of a tank seal, a flange

or NPT or

. See “Ordering Information” on page A-21).
Flange mating face dimensions follow ANSI B 16.5, JIS B2220, and
EN 1092-1 standards for blind flanges. Fisher and Masoneilan flanges are
also available.
Certain models of flanged Alloy and PTFE covered probes have a tank
connection design with a protective plate of the same material as the probe, to
prevent the 316L / EN 1.4404 SST flange from being exposed to the tank
atmosphere.
The following diagrams give process temperature (maximum product
temperature at the lower part of the flange) and pressure ratings for tank
connections:
• Standard (Std)
• High Temperature and High Pressure (HTHP)
• High Pressure (HP)
• Cryogenic (C)
NOTE!
For standard tank connection, the final rating depends on flange and O-ring
selection.
The C version can manage lower temperatures (-321 °F/-196 °C) than the
Standard, HP, and HTHP versions.
