Over 1000 psi – entire system must be 316 stainless steel.
Applicable only to hydrogen.

Monel and 316 stainless steel are acceptable for oxygen service, provided the
instrument has been cleaned for oxygen service and is free from oil.

Pressure Gauge

The media being measured must be
compatible with the wetted parts of the
pressure instrument. To use the chart
below, locate the media whose pressure
is to be measured and select a suitable
material from those available. Diaphragm
seal information is contained in Bulletin
DS-1. This is a simplified chart and

assumes the media temperature is
below 200°F.

PLUS! option, throttling

devices and/or a liquid-filled instrument
are recommended in applications with
pulsation or vibration. These recommen-
dations are only a guide, as service life is
dependent on temperature, concentra-
tions, catalysts that may be added, or

other conditions beyond our control.
Consult Stratford, CT customer service
for specific applications and for any
media not listed. More complete corro-
sion guide available on our website at
www.dresserinstrument.com in the
Application Data Section.

Any standard Bourdon tube material may be used in conjunction with a diaphragm
seal, but the gauge selection should take into consideration the corrosive environment
in which it is to operate. For diaphragm seals see Bulletin DS-1.
