3. For insulated systems, ensure that you insulate the device as far as possible to the lower
edge of the enclosure:
0D[
In this way, you avoid a defect in the device or the loss of explosion protection for Ex devices.
You can find the permissible temperature values in the section Technical data (Page 199).
4. To guarantee secure and vibration-free installation of the pressure transmitter, fasten it to
5.2.2
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 238).
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
