The extraction point must be suitable for extracting a representative specimen flow.
In the case of emission monitoring systems the extraction point is specified by the
responsible technical inspection authority.
•
Install the wall tube with mounting flange (DN 65, PN 6, type A according to
DIN EN 1092-1; not supplied) at the extraction point in such a way that the sampling
probe tube can be easily installed and removed (see Figure 1).
•
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 (see Figure 1).
Observe the separate instructions for installation of probe tube type 40W on page 27!
