Analyzer system: Installation site requirements
CAUTION
The analyzer system must not be installed in hazardous locations.
Choosing the extraction point
The extraction point must be suitable for extracting a representative speci-
men flow.
In case of emission monitoring of exhaust gases, the extraction point is
specified in accordance with responsible technical inspection authority, e.g.
classification society.
Wall tube installation
Install the wall tube with mounting flange (DN 65, PN 6, facing
type A to EN 1092-1; not supplied) at the extraction point in
such a way that the sampling probe tube can be easily in-
stalled and removed. The sampling probe tube must be easily
accessible to allow maintenance work to be performed. Align
the boreholes of the mounting flange in relation to the flow
direction of the process gas.
Short gas paths
The analyzer cabinet should be installed as close as possible to the sampling
site. A short sample gas line results in short T90 times.
The sample gas line length is limited to 30 meters with 230 VAC power on
account of pressure drop build-up in the line and the required electrical fus-
ing.
Protection from adverse conditions
Protect the analyzer cabinet against
•
Water spray
•
Contact with chemicals
•
Strong sunlight and heat radiation
•
Strong air currents
•
Heavy dust load
•
Corrosive atmospheres
Installation indoors
The analyzer system is intended for installation aboard a ship. Thereby, the
installation location height is naturally limited to sea level.
The analyzer cabinet is only suitable for installation indoors. An air-condi-
tioned room is recommended.
Protection class: IP54
