LDS 6 – In-Situ Laser Gas Analysis for Extreme Process Conditions
Reliable gas measurement where temperatures and dust levels are at their highest
When gas analysis must be performed directly in furnaces, reactors, or kilns with extreme temperatures and harsh conditions, Siemens LDS 6 delivers robust and accurate in-situ laser measurements without the need for sample extraction.
In-situ laser gas analysis designed for extreme environments
The Siemens LDS 6 is an in-situ gas analyser based on laser absorption spectroscopy, specifically engineered for very high process temperatures and heavy dust loads.
By measuring directly across the process duct or furnace, LDS 6 eliminates sample handling and provides fast, representative gas concentration data even under the most demanding conditions.
The analyser is widely used in high-temperature industrial processes where conventional extractive systems are impractical or unreliable.
Key features and capabilities for harsh industrial processes
LDS 6 is built to deliver stable measurements where other technologies reach their limits.
- In-situ measurement across the process with no gas sampling
- Laser-based spectroscopy for selective and reliable gas detection
- Designed for extremely high temperatures, such as furnaces and reactors
- Handles high dust loads without clogging or signal degradation
- Fast response time for real-time process control
- Minimal maintenance requirements due to the absence of sample systems
- Robust industrial design for continuous 24/7 operation
Typical applications in high-temperature processes
LDS 6 is used in industries where gas analysis must withstand extreme thermal and mechanical stress.
- Steel and metal production furnaces
- Cement kilns and clinker coolers
- Chemical reactors and high-temperature process units
- Glass production and melting furnaces
- Waste incineration and thermal treatment processes
- Combustion optimization in extreme environments
Benefits for you – dependable data in the most demanding conditions
With LDS 6, you gain access to gas concentration data that would otherwise be difficult or impossible to measure reliably.
- Accurate measurements directly in the hot process zone
- Improved process control in high-temperature applications
- Lower maintenance effort compared to extractive solutions
- High system availability even in dusty and aggressive environments
- Reduced installation complexity with no sample lines or conditioning
