4 .1 General instructions
With instruments with threaded process fitting, suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.
Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
fitting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
4 .2 Collar or adapter flange
For mounting the instrument on a socket, a combi compression flange
for DN 80 (ASME 3" or JIS 80) is also available for retro fitting.
Optionally, the instrument can be also equipped with an adapter flange
from DN 100 (ASME 4" or JIS 100).
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar flange can be placed directly over the
housing. With the aluminium double chamber housing, retroactive
mounting in this way is not possible - the mounting type must be
specified with the order.
You can find drawings of these mounting options in chapter
"D
imensions".
