Measuring System LT2
The Universal Solution for O2 and CO/H2 Measurement
Your advantages at a glance:
- In combination with LS2:
Measurement of oxygen (O2) - In combination with KS1D: measurement of oxygen (O2) and detection of oxidising flue gas components CO/H2 (COe)
- Measurements for monitoring and optimization
- Proven in operation and low maintenance
- SIL1 in accordance with DIN EN 61508
Applications:
For connecting the following probes:
LS2/KS1D ECO, LS2/KS1D-BF, LS2/KS1D Ex, LS2/KS1D KAF
The LAMTEC Lambda Transmitter LT2, in combination with the LAMTEC probes LS2 and KS1D, is a universally applicable microprocessor-based measuring device. It is the all-round alternative to the LT3. In combination with the KS1D probe, the LT2 is used for the simultaneous measurement of the O2 concentration and detection of oxidising gas components CO/H2 (COe) in flue gases of combustion plants. The measured value COe represents a sum signal of all oxidisable flue gas components. However, it can also be used with the classic LAMTEC LS2 probe for oxygen measurement.
The LT2 can optionally control the purging and automatic calibration of the probe. All available LS2 and KS1D probes, such as the Ex probe or the KAF probe, can also be connected to it.
If required, the LT2 is also available with an EX enclosure with the following approval:
- Ex II 2G Ex d IIB+H2 T5 Gb
- Ex II 2D Ex tb IIIC T100 °C Db
- Labelling according to IECEx:
- Ex II 2G Ex d IIB+H2 T5 Gb
- Ex II 2D Ex tb IIIC T100 °C Db
A SIL 1 certificate in accordance with DIN EN 61508 for safe measurement and limit value output in combination with the KS1D probe is available as a special configuration of the LT2.

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.
