Diaphragm seal versions
•
The protective cap of the diaphragm seal should only be removed just
before mounting in order to protect the diaphragm.
•
The diaphragm of the diaphragm seal of the Barcon must not be dented or
cleaned with pointed or hard objects.
•
The diaphragm seal and the pressure sensor together form a closed and
calibrated system which is filled with filling fluid through a hole in the upper
part of the sensor. The following rules should be observed:
- This hole is sealed and is not to be opened.
- The instrument should only be turned by the diaphragm seal at the point
provided and not by the housing.
