4. For insulated systems, ensure that you insulate the device as far as possible to the lower edge
of the enclosure.
In this way, you avoid a defect in the device or the loss of explosion protection for Ex devices.
You can nd the permissible temperature values in the section Technical data (Page 61).
5. To guarantee secure and vibration-free installation of the pressure transmitter, fasten it to a
mounting bracket (Page 27).
Level
You can nd details on how to mount the device with level in the section Installation (level)
(Page 28).
4.3 Securing the device with mounting bracket
Using the mounting bracket, you can secure the pressure transmitter as follows:
• On a mounting range
• On a vertical or horizontal pipe (Ø 50 to 60 mm)
Notes
• Install the device so that the pressure transmitter and the dierential pressure lines are not
subject to dierent vibrations. Otherwise there is a danger that the dierential pressure lines
will rupture.
• When securing, observe the torques in the section Torques (Page 80).
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
