Oxygen applications (gaseous)
Oxygen and other gases can react explosively to oils, grease and plastics, such that, among
other things, the following precautions must be taken:
• All components of the plant, such as the measuring devices, must be cleaned according
to national requirements.
• Depending on the materials used, a certain maximum temperature and a maximum
pressure must not be exceeded for oxygen applications.
Cleaning of the measuring device (not device accessories) is offered as an optional service.

Measuring device without a manifold
• –40 to +85 °C (–40 to +185 °F)
Lower temperatures are optionally available.
• Pay attention to the process temperature range of the seal
Measuring device with a manifold
The maximum permitted process temperature at the manifold is 110 °C (230 °F) (limited
by IEC standard).
For process temperatures >85 °C (185 °F) where non-insulated side flanges are installed
horizontally on a valve manifold, a reduced ambient temperature applies up to a maximum
ambient temperature calculated according to the following formula:
T
Ambient_Temperature_max
= 85 °C − 2.8 ⋅ (T
Process_Temperature
− 85 °C)
T
Ambient_Temperature_max
= 185 °F − 2.8 ⋅ (T

T
Ambient_Temperature_max
