WARNING!
Physical injuries and damage to property and the
environment caused by media escaping under high
pressure
With the pressurisation of the instrument, as a result of
poor sealing of the process connection, media under high
pressure can escape.
Due to the high energy of the media that can escape in
the event of a failure, the possibility of physical injuries and
damage to property exists.
▶
The sealing of the process connection must be carried out
expertly and checked for leak tightness.
6.1 Mechanical connection
In accordance with the general technical regulations for pressure gauges
(e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges").
Instruments must be grounded via the process connection.
This is why electrically conductive sealing should be used at the process
connection. Alternatively, take other measures for grounding. Measures
for grounding applied ex works (e.g. welding spots or fuse plates) must
therefore be used to integrate the devices into the equipotential bonding
system and must not be removed under any circumstances. Ensure that
the measures for grounding are reinstalled after dismounting (e.g.
replacing the device).
