SIL2 capable measuring system LT3-F (electronics) and KS1D (sensor) as a system component of the CO/O2 regulation. Usable only in connection with BT300/ETAMATIC/FMS/VMS. The Lambda Transmitter LT3-F is an electronic evaluation device, that was developed for the continuous measurement of O2 concentration and the oxidizing flue gas particles (CO/H2) in the super-stichiometric range in connection with the combination probe KS1D.  

Permissible fuels:

  • Residue free gaseous hydrocarbons (SIL 2 capable)
  • Domestic fuel (SIL 2 capable)
  • Lignite/coal (not SIL 2 capable)
  • Biomass (wood) (not SIL 2 capable)


Direct measurement in combustible gases are not possible.
