Description
Nominal size 100 and 160 mm
„
The instruments measure the pressure by means of resilient diaphragm
„
measuring elements. The reference point is absolute pressure "zero".
In addition, the enclosing components of
„
models 53X.30.1X0 and 53X.36.1X0 also
meet the requirements of EN 837-1, relating to
safety pressure gauges with a solid baffle wall
(code S3).
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.
Scope of delivery
Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport
Check the instrument 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).
