Mounting Promag H sensor
The Promag H sensor is delivered with the process connection already mounted.
The various process connections are fastened to the sensor with 4 or 6 screws.
Seals / Screw tightening torques
When mounting the process connectors,
make sure that the seal is free of dirt
and correctly centered. The screws have
to be tightened.
The process connector forms a metal
connection with the sensor, to guarantee
a pre-defined seal compression.
The gaskets must be replaced at
frequent intervals!

Welding the sensor into the pipework (welded nipple)
If the sensor is directly welded into the pipework, we recommend the following
procedure:
Caution!
The electronics may be destroyed! Take care that the welding ground is not via
the Promag 33 H sensor or housing.
1. Fasten the Promag H sensor with some spot welds into the pipe.
2. Loosen the screws at the process-connector flange and remove the sensor from
the pipe; make sure that the seal is also removed from the process connector.
3. Weld the process connector into the pipe.
4. Once again install the sensor into the pipe; making sure everything is clean and
the seal is correctly positioned.
Note!
•
If the welding process is correctly executed in thin-walled food piping, the seal will
not be damaged by the heat, even when mounted. Nevertheless, we recommend re-
moving the sensor and seal first.
•
For the disassembly, the pipe has to be spread by about 4 mm.
Caution!
Note!
