Purpose

The LT2 Lambda transmitter is a universal, microprocessor based O2 measuring instrument for the direct measurement of O2 concentration in exhaust gases from oil and gas combustion facilities in the superstoichiometric domain ( λ >1), in conjunction with the LS2 Lambda probe.

Optionally, the KS1D combination probe can be activated to record combustible gas components (CO/H2) - see separate publication. It is possible to set up direct coupling with the compound/firing management system and ETAMATIC. This allows the implementation of an improved control procedure for optimising oil and gas combustion facilities, and for automatic combustion system tuning to variable combustion conditions.

In addition to O2 measurement, the LT2 Lambda transmitter also offers the following functions:

  • Measurement of flue gas and air temperature intake, and calculation of combustion efficiency
  • Detection of unburnt residue (CO/H2), shown as CO equivalent (COe)
  • Calculation and display of CO2 concentration
  • Load-dependent and fuel-specific boundary curves / limit values
  • O2-regulation
  • Combustion chamber pressure regulation
  • Field bus connection
