Measuring System LT1
The Solution for O2 Measuring
Your advantages at a glance:
- Measurements for monitoring and optimisation; also for demanding combustions
- Highly accurate measuring of oxygen (O2) up to 21 vol.%
- Linear probe signal (direct current [mA]) with fixed physical zero point
- No special test gases required, automatic calibration with ambient air
- Automatic aging compensation of the ZrO2 measuring cell
- Up to 1.400 °C with ceramic sampling
- SIL 1 according to DIN EN 61508, parts 1-7
Applications:
For connection to Lambda Probe LS1
The LAMTEC Lambda Transmitter LT1 in combination with the LAMTEC probe LS1 is a universally applicable microprocessor-based measuring device. This measuring transducer has been specially developed for precise measurement of O2 concentrations in flue gases from combustion plants in the superstoichiometric range (λ > 1).
For example ...
- in combustion exhaust gases
- in furnace atmospheres
- etc.
The system, which consists of LT1 and LS1, has a modular design and offers tried and tested solutions for most applications. For example, the LT1 can control the purging for high dust applications and the automatic calibration of the probe by means of a suitable combination of probe installation fitting and gas extraction (GED).

Measuring System LT1
The Lambda Transmitter LT1, in combination with the Lambda Probe LS1, is a universally applicable modular measuring system for direct and highly accurate measurement of O2 concentration up to 21 % in gases in the superstoichiometric range.
Measuring System LT2
The Lambda Transmitter LT2 is the all-round solution for simultaneous CO/H2 and O2 measurement in conjunction with the KS1D combination probe or for pure O2 measurement with the LS2 probe. From automatic adjustment to purging in dusty applications, this system can be used for almost all needs and marginal conditions.
Measuring System LT3
The LT3 Lambda Transmitter is the cost-effective solution for simultaneous CO/H2 and O2 measurement in conjunction with the KS1D combination probe or for pure O2 measurement with the LS2 probe.
Measuring System LT3-Ex
The Lambda Transmitter LT3-Ex is based on the LT3. Due to the pressure resistant enclosure (Ex d) it can be used in conjunction with the KS1D-Ex or LS2-Ex probe in hazardous areas zone 1 and zone 2 for simultaneous measurement of O2 and CO/H2 or for selective O₂ measurement with the LS2 lambda probe in potentially explosive areas of Zone 1 and Zone 2.
Measuring System LT3-F
The LT3-F Lambda Transmitter, in combination with the Combination Probe KS1D and the LAMTEC burner management system, is a fail-safe system (SIL 2) for COe combustion optimization. The fault safety is only valid for the complete system.
Measuring System LT4
The Lambda Transmitter LT4, in conjunction with the KS1D combination probe, is a fail-safe system (SIL 3) for simultaneous monitoring of O2 concentration and oxidizing gas components (CO/H2). It is the only SIL 3-certified flame monitoring system on the market.
Measuring System NT1
The NOx Transmitter NT1, in combination with the Combination Probe KS2DNOx, is the innovative package solution for simultaneous NOx and O2 measurement in exhaust gases of combustion plants. The measurement is performed directly in the exhaust gas (in situ), therefore no measurement gas preparation is necessary. Up to 4 probes can be connected.
