LS2/KS1D-Ex
The LAMTEC Lambda Transmitter LT3-Ex in combination with the LAMTEC probes type LS2 and KS1D-Ex is a universally applicable measuring device based on microprocessor technology. It is designed in the ignition protection type "pressure resistant enclosure" (Ex d) or "increased safety" (Ex eb). This allows the entire system to be used in hazardous areas, both in zone I and zone II. This transmitter was specially developed for the simultaneous measurement of O2 concentration and detection of oxidising gas components COe (CO/H2) in flue gases from combustion systems in the superstoichiometric range (λ > 1) using the KS1D-Ex probe. However, it can also be used with the LAMTEC LS2-Ex probe for pure oxygen measurement. The measured value COe - e = equivalent represents a sum signal of all oxidisable flue gas components.
