Subject to the process connection used and the process connection temperature.
Guidelines for maximum operating pressure
For more data, refer to
≥1.4
IEC 60529: IP66 / IP68 (0.1 barg / 1.45 psig)
NEMA 250: NEMA type 4X - 6 (housing) and type 6P (antenna)
60 m/min / 196 ft/min
The nominal diameter (DN) should be equal to or larger than the antenna diameter.
If the nominal diameter (DN) is smaller than the antenna, either:
– provide the means to adapt the device to a larger process connection on the tank
(for example, a plate with a slot), or
– use the same process connection, but remove the antenna from the device before
installation and fit it from inside the tank.
Make sure that there are not any obstructions directly below the process
connection for the device. For more data, refer to

This is the maximum range. The feedthrough temperature limits must agree with
the temperature limits of the gasket material and antenna type.
