3.
Only pull the protective cap off shortly before installation. Make sure that the diaphragm of the process connection
does not get damaged (only for flush process connections).
WARNING!
Danger to life due to loss of explosion protection from damaged process connection
The diaphragm of the flush process connection is a safety-relevant component. If it is damaged, the
explosion protection is no longer guaranteed. Through any explosion resulting from this, there will be
a high danger to life.
■
Before commissioning the pressure transmitter, the diaphragm of the flush process connection
should be checked for visible damage.
■
Leaking fluid is indicative of a damaged diaphragm.
■
Protect the diaphragm from contact with abrasive media and against any impacts.
■
Observe the specifications for the use of the pressure measuring instrument in combination with
aggressive/corrosive media and for avoiding mechanical hazards.
■
Only use the pressure transmitter if it is in perfect condition with respect to safety.
4. Seal the process connection as follows.
Parallel threads
For sealing, use flat gaskets, lens-type sealing rings or
WIKA profile sealings at the sealing face
.
Tapered threads
For sealing, the thread is wound with additional sealing
material, e.g. PTFE tape.
