Mounting Promag 30 H
Length and dimensions
See chapter 7.1 “Dimensions and weights”.
Mounting
The various process connectors are fastened to the sensor with 4 or 6 screws. As a
rule, the promag H sensor is supplied with works-monted process connectors.
When mounting the process connectors,
please make sure that the packing is
free of dirt and correctly centered.
The screws have to be tightened.
The process connector forms a metal
connection with the sensor, so the
packing is not compressed.
Welding the sensor into the pipework
If the sensor is directly welded into the pipework, we recommend that you:
1. Fasten the Promag H sensor with some welding points into the pipe;
2. Loosen the screws at the process-connector flange and remove the sensor from the
pipe; make sure that the gasket is also removed from the process connector;
3. Weld the process connector into the pipe.
4. Once again install the sensor into the pipe; make sure everything is clean and
the gasket is correctly positioned.
Note!
If the welding process is correctly executed, the gasket will not be damaged by the
heat, even when mounted. Nevertheless, we recommend you remove the sensor and
gasket first.
For the mounting, the pipe has to be opened by about 4 mm.
Caution!
Please note that the grounding of the welding set does not occur by way of the
Promag 30 H (sensor or transmitter). If you fail to observe this, the electronics might
be destroyed.
