The gas sampling unit consists of filter housing, gas sampling tube, weatherproof enclo‐
sure and optional pre-filter.
Application area
The gas sampling unit SFU is used for flue gas extraction and filtering for analysis in a
measuring system.
The flue gas is taken via a gas sampling tube and fed to a measuring system after filtra‐
tion.
The gas sampling tube is optionally available in various lengths.
As an option, the gas sampling tube contains a pre-filter at the probe tip.
For maritime applications, unheated gas sampling tubes without pre-filters are used.
Measuring system
The gas sampling unit is operated on a SICK measuring system. Thus, only this operat‐
ing mode is described in this Manual.
Applications with customer-owned peripheral devices are not planned.
