Prerequisites for assembly
An effective gas exchange is required in the optical path to ensure adequate response
times and avoid condensation.
●
Place the TRANSIC111LP probe as far as possible in the process. The recommended
minimum depth is 5 cm.
●
In case of an axial installation in a tube or flange piece, the tube diameter must be wide
enough to allow gas exchange. Here, the recommended diameter is minimum 60 mm.
●
The dewpoint can be underflown when the probe is only inserted a little into the process
or the temperature difference between environment and process is too high (>30 °C). In
these cases, the flange area must be insulated or heated.
3.2.3
Installation angle
Install the TRANSIC111LP at a self-draining angle. When the process is very wet, ensure no
liquid can reach the beam path.
●
The probe can be tilted freely when the process gas is dry (the process temperature is
much higher than the dew point of the gas) so that there is no risk of condensation.
●
When using the sample gas cell: It is possible that measured values for high O
2
concentrations can depend on the flow rate when the probe and sample gas cell are
installed in vertical direction.
▸
Do
not
install the measuring probe vertical.
