Siemens 7MF0330 - Fastening with the Mounting Bracket

Procedure
1. Attach the pressure transmitter to the process connection.
Use an appropriate tool (e.g. open-ended wrench with width across flats 36). Otherwise,
the measuring cell may be damaged.
2. Turn only on the key area above the process connection.
Caution: If you turn the pressure transmitter on the housing, the measuring cell may be
damaged.
3. To guarantee secure and vibration-free installation of the pressure transmitter, fasten it to
a mounting bracket (Page 29).
4.2.3 Fastening with the mounting bracket
Introduction
You mount the pressure transmitter with the mounting bracket as described below:
● On a mounting range
● On a vertical or horizontal pipe (Ø 50 to 60 mm)
When securing, observe the torques in the section Torques (Page 101).
Note
Install the device so that the pressure transmitter and the differential pressure lines are not
subject to different vibrations. Otherwise there is a danger that the differential pressure lines
will rupture.
Example 1: Pipe mounting of pressure transmitter (gauge pressure series)
The mounting bracket for the gauge pressure series includes, among other things:
● 2 screws
● One pipe clamp with nuts
● Washers
Mount the pressure transmitter as follows:
