6. Commissioning, operation
Installation
Do not damage the diaphragm; scratches on the diaphragm (e.g.
GB
from sharp-edged objects) are the main causes of corrosion
For sealing, choose appropriate seals
For flange mounting, use a seal with a sufficiently large internal
diameter and centre it; contact with the diaphragm leads to measur-
ing errors
When using soft or PTFE seals, observe the instructions of the seal
manufacturer, particularly with regards to tightening torque and load
cycles
For installation, in accordance with the fitting and flange standards,
the appropriate fastenings, such as screws and nuts, must be used
Permissible ambient and operating temperatures
When mounting the pressure gauge it must be ensured that, taking
into consideration the influence of convection and heat radiation,
no deviation above or below the permissible ambient and medium
temperatures can occur. The influence of temperature on the indication
accuracy must be observed.
In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
Permissible vibration load at the installation site
The instruments should always be installed in locations free from
vibration
Commissioning
During the commissioning process pressure surges must be avoided
at all costs.
