Requirements for the installation point
If the measuring point is not adequately stable a measuring instrument
support such as a bracket or flange should be used for fastening (and
possibly via a flexible capillary line). If the pressure gauge is exposed to
vibration or pulsating pressure or both, then a liquid filled pressure gauge
may provide considerably better performance and readability. Instruments
should be protected against coarse dirt and wide fluctuations in ambient
temperature.

Admissible ambient and working 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 display accuracy must be
observed.
