WIKA operating instructions pressure gauge model 5 per ATEX
■ The diaphragm (1) separates the media
chamber (3) and the reference pressure
chamber (2) with absolute pressure zero
■ Pressure differential between media chamber
(3) and reference pressure chamber (2) will
deflect the diaphragm (1)
■ In case of an overpressure overload the
pressure element will be protected by a
contoured metal bolster
■ The deflection is transferred from the
pressure chambers through bellows or
corrugated tubes (4), transmitted to the
movement via the link (5) and indicated.

5. Transport, packaging and storage
5.1 Transport
Check the absolute 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.
