Requirements for the installation point
If the measuring point is not adequately stable a measuring instrument
GB
support such as a bracket or fange should be used for fastening (and
possibly via a fexible capillary line). If the pressure gauge is exposed to
vibration or pulsating pressure or both, then a liquid flled pressure gauge
may provide considerably better performance and readability. Instruments
should be protected against coarse dirt and wide fuctuations in ambient
temperature.
Installation
Nominal position per EN 837-1 / 9.6.7 Figure 9: 90° ( ⊥ )
■
Process connection bottom or rear!
■
In order to avoid any additional heating, the instruments must not be
■
exposed to direct solar irradiation while in operation!

Admissible ambient and working temperatures
When mounting the pressure gauge it must be ensured that, taking into
consideration the infuence of convection and heat radiation, no deviation
above or below the permissible ambient and medium temperatures can
occur. The infuence of temperature on the display accuracy must be
observed.
