If the line to the measuring instrument is not adequately stable, an
„
instrument mounting bracket should be used for fastening.
EN
If vibrations cannot be avoided by means of suitable installation,
„
instruments with case filling should be used.
For outdoor applications, the selected installation location has to be
„
suitable for the specified ingress protection, so that the instrument 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!
To ensure that the pressure can be safely vented in the case of failu-
„
re, for the correct function of the blow-out back, a minimum distance
of 20 mm from any object must be maintained.
WARNING!
Physical injuries and damage to property and the
environment caused by the back blowing out in the
event of a failure
Due to the high energy in the back, if it is blown out in the
event of a failure, there is a risk of physical injuries or damage
to property through the ejected back and the media that
would then escape.
