System overviewLambda-Transmitter LT 1The LT 1 Lambda transmitter is a universal, microprocessor-based O 2 measuringinstrument for the direct measurement of O 2 concentration in exhaust gases from oiland gas combustion facilities in the super-stoichiometric domain (l>1), in conjunctionwith the LS 1 Lambda probe.For the collection of combustible gas components (CO/H 2 ) the Combination probe KS1 can be connected as an option.• - in combustion exhaust gases• - in industrial waste gases• - in furnace atmospheres• - in process gasesAdvantages:Linear probe signal (direct current [mA]) with fixed physical zero pointNo special calibration gases required, automatic calibration with ambient air(21% by vol. O 2 )Measuring accuracy better than 0.2 vol.% O 2 over the entire measuring range0…21 vol.% O 2No gas purification necessaryNo reference gas requiredSettling time

Measuring PrincipleLambda-Transmitter LT 1Measuring principleO 2 concentration is continuously measured by the LS 1 Lambda probe (see separatepublication DLT6061).A small quantity of gas (approx. 0.5 l/h) is drawn directly from the measured gasthrough a capillary tube.A 7-wire plugged cable and a Teflon hose connect the LS 1 probe to the LT 1 Lambdatransmitter.The probe's signal is analysed in the LT 1 Lambda transmitter, using the latestmicroprocessor technology. A serial interface, a monitor output0…2.55 V DC = 0…25.5 vol. % O 2 , up to 4 analogue outputs0/4…20 mA, 0…10 V and up to 7 digital outputs are available to output the measuredvalues and operating conditions.Internal LEDs provide operational information and indicate any system faults identifiedby the diagnostic functions.The LT 1 Lambda transmitter is provided with the following functions:• Automatic testing and calibration of the LS 1 probe against the ambient air.• Automatic ageing compensation of the ZrO 2 cell through determination of the cell'sinternal resistance and adjustment of the heater output.• Compensation for the effect of gas composition on gas flow through in highlyunbalanced measured gases, such as flue gas after wet scrubber or in vapoursresulting from fluctuating sound velocity and density, compared with conditionsduring calibration (air).• Intermittent gas pump with automatic calculation of optimum pump running time.Optional long-life mode with limited measuring accuracy.• Intelligent, optionally automatic cold-start delay, adjustable between5…120 minutes.• Integral maintenance switch.• LAMTEC SYSTEM BUS for direct coupling to the LAMTEC linked burner controlsystems VMS / FMS / ETAMATIC, for O2 optimisation and LT2 Ks1 for thedetection of nonburned CO/H 2 in waste combustion gases shown as COequivalent(COe)• A RS 422 interface is also available as an alternative to the LAMTEC SYSTEMBUS, for coupling to the customer's systems.• In addition, a RS 232 interface is available for PC-based remote control inconjunction with the (optional) service and diagnostic software.
