5. Transport, packaging and storage
5.1 Transport
Check the differential pressure gauge for any damage that may have been
caused by transport. Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.
change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage
Storage temperature: -20 ... +60 °C
In order to prevent damage, the following points should be noted for the
storage of the pressure gauges:
■ Leave the pressure gauges in their original packaging
■ Following any possible removal of the measuring instruments, e.g. for testing,
the instrument should again be stored in its original packaging
Avoid exposure to the following factors:
■ Direct sunlight or proximity to hot objects
■ Mechanical vibration, mechanical shock (putting it down hard)
■ Soot, vapour, dust, humidity and corrosive gases
■ Potentially explosive environments, flammable atmosphere
WARNING!
Before storing the instrument (following operation), any residual
media must be removed. This is of particular importance if the
medium is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc.
6. Commissioning, operation
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").
■ Process connections 2 x G 1/4 female, lower mount (LM), in-line, centre
distance 26 mm, operating position NL 90 (nominal position) per DIN 16257
(i.e. vertical dial), design the threads of the pressure connection in accordance
with EN 837-3 (section 7.3.2).
