6.1 Mechanical connection
In accordance with the general technical regulations for pressure gauges (e.g.
■
EN
EN 837-2 "Selection and installation recommendations for pressure gauges").
Mount pressure connections in accordance with affixed symbols: ⊕ high pres-
■
sure, ⊖ low pressure.
Process connections 2 x G ¼ female thread, lower mount, in-line, centre
■
distance 26 mm, operating position NP 90 (nominal position) per DIN 16257
(i.e. vertical dial), design the threads of the connection shanks preferably in
accordance with EN 837-3 (section 7.3.2).
Prior to the installation of the instrument, clean the measuring lines thoroughly
■
by tapping and blowing or flushing.
Protect the measuring instruments from contamination and high temperature
■
changes!
Mount the instrument free from vibration and make alignment so that it is easy
■
to read. It is recommended that a shut-off device is interposed between the
pressure tapping point and the instrument, which will enable the replacement
of the instrument and a zero point check while the plant is running. Protect the
instrument against coarse dirt and wide fluctuations in ambient temperature.
For sealing the connections, use flat gaskets, lens-type sealing rings or WIKA
■
profile seals. Connections with LH-RH adjusting nut or union nut enable the po-
sitioning of the instrument for better readability. For the mounting or dismount-
ing of the instrument, the required force must not be introduced via the case,
but only on the spanner flats of the connection nozzle!
