6. Commissioning, operation
When a blow-out device is fitted to a pressure gauge, it must be
protected against being blocked by debris and dirt.
With safety pressure gauges (see dial symbol
space behind the blow-out back is at least 15 mm.
Requirements for the installation point
If the measuring point is not sufficiently stable a measuring instru-
ment support such as a bracket or flange should be used for fastening
(possibly via a flexible capillary). If vibrations cannot be avoided by
taking suitable measures during installation, liquid-filled instruments
should be used. Instruments must be protected against coarse dirt and
wide fluctuations in ambient temperature.

After mounting, set the compensating valve (if available) from

CLOSE to OPEN. The version of the vent
valve depends on the model and can deviate
from the illustration!
For outdoor applications, the selected installation location has to
„
be suitable for the specified ingress protection, so that the pressure
gauge is not exposed to impermissible weather conditions.
In order to avoid any additional heating, the instruments must not be
„
exposed to direct solar irradiation while in operation!
