4.1 Application conditions
Before mounting, setup and operation, take note that the pressure
transmitter as well as the chemical seal were selected according to
measuring range, version and material suitable for the process condi-
tions. The load limits must be maintained in order to guarantee the
specifiedaccuracy.
Caution:
In dangerous substances such as e.g. oxygen, acetylene, combusti-
ble or toxic products as well as in refrigerating plants, compressors,
etc., the pertinent instructions must be observed in addition to the
general regulations.
Take note of the following issues in respect to the process and ambi-
ent temperature:

4.2 Oxygenapplications
Oxygen and other gases can be explosive when brought into contact
with oils, grease and plastics, so the following measures must also be
taken:
•
All components of the plant, such as e.g. measuring instruments
must be cleaned oil and grease-free for oxygen applications
accordingtotherequirementsofBAM(FederalInstituteforMateri-
als Research and Testing)
•
Max. temperatures and pressures determined with oxygen appli-
cations must not be exceeded, see chapter "Technical data" and
"Chemicalsealswithvacuumapplications", also keep sealing
material in mind
Danger:
Instruments for oxygen applications must be unpacked just before
mounting.Afterremovingtheprotectivecoveroftheprocessfitting,
