3. Tighten screws with the necessary torque (see chapter "
Techni-
cal data
", "
Torques
")
Note:
We recommend retightening the screws at regular intervals depend-
ing on the process pressure and temperature. This will maintain the
sealing properties of the antenna encapsulation against the process.
PTFE threaded adapters are available for VEGAPULS 6X with thread
G1½ resp. 1½ NPT. Due to this, only PTFE is in contact with the
medium.
