6. Commissioning, operation
For parallel threads, use flat gaskets, lens-type sealing rings or WIKA
profile sealings at the sealing face . With tapered threads (e.g. NPT
threads), sealing is made in the threads , using a suitable sealing
material (EN 837-2).
The torque depends on the sealing used. In order to orientate the
measuring instrument so that it can be read as well as possible, a
connection with LH-RH union or union nut should be used.
When a blow-out device is fitted to a pressure gauge, it must be protect-
ed against being blocked by debris and dirt.
6.2 Requirements for the installation point
If the line to the measuring instrument is not adequately stable, an instru-
ment bracket should be used for fastening (and possibly via a flexible
capillary). If vibrations cannot be avoided by means of suitable instal-
lation, instruments with liquid filling should be used. The instruments
should be protected against coarse dirt and wide fluctuations in ambient
temperature.
