2 Install the weld-in adapter
Use the weld-in adapter to install transmitters with G1 process
connections to containers or pipes.
Prerequisites
After welding, allow the adapter to cool before installing. Do not weld
the adapter to the container or pipe with the transmitter connected.
Procedure
1. Bore a hole that has the outside diameter of the adapter in the
pipe or container wall.
Maximum oversize: 0.008 in (0.2 mm)
2. Weld the adapter.
Note
While welding, prevent the adapter from warping.
a) Turn the marking (1) (marking may vary) to the
position shown below for the display of the screwed
transmitter.

b) Fix the adapter in several spots with a sufficient
adhesive force.
Apply the fixing points at equal distances opposite
each other.
c) Apply the welding seams between the fixing points
opposite each other.
Ensure sufficient and even distance between the
individual sections to avoid glowing through or
warping of the adapter caused by overheating.
3. Allow the adapter to cool.
4. If used, remove the welding mandrel.
5. Remove deposits from the thread.
