Page 10: Protection Against Emissions From Gas Carrying Channels
For Your Safety Protection Against Emissions from Gas Carrying Channels Protect against gas leakage from the gas-bearing channel The Lambda Probe LS2-K is fitted directly to the gas-bearing channel via a counterflange. If the Lambda Probe LS2-K is dismantled, depending on the plant but particularly in the case of excess pressure, aggressive and / or hot gas can seep out of the channel and this could pose a serious health hazard to an unprotected operator if suitable safety measures have not be taken previously. -

Appendix 10.8 Wet/Dry Measurement Deviations, Conversion Table NOTICE The LT2 carries out measurements directly in the humid flue gases (wet measurement). When extractive devices are used, flue gases are removed and prepared. "Dry Measurements" are normally used here, since the humidity has been extracted from the flue gas. As a result, O measurement values vary (see diagrams below). -
