Siemens LDS 6 is a diode laser gas analyzer with a measuring principle based on the specific light absorption of different gas components. LDS 6 is suitable for fast and non-contact measurement of gas concentra tions in process or flue gases. One or two signals from up to three measuring points are processed simultaneously by the central analyzer unit. The in situ optics enclosures at the individual measuring points are connected to the central unit via fiber optic cables, so that the distance between the installation site of the central unit and the measuring points can be up to 700 m. The optics enclosures are designed for operation under harsh environmental conditions and contain a minimum of electrical components.
Applications
- Process optimization

Special applications
In addition to the standard applications, special applications are available on request. These contain both an expansion of the tem perature and pressure range, as well as an expansion of the concen tration measuring range. Furthermore, other gas species can be measured using special applications.
The in situ gas analyzer LDS 6 is characterized by a high availability and unique analytical selectivity. It is optimally suitable for numerous applications. LDS 6 enables the measurement of one or two gas components or – if desired – the gas temperature directly in the process:
- With high dust load
- In hot, humid, corrosive, explosive, or toxic gases
- In applications showing strongly varying gas compositions
- Under harsh ambient conditions at the measuring point
- Highly selective, i.e. mostly without cross-sensitivities
LDS 6 properties:
- Low installation workload
- Minimum maintenance requirements
- Extremely rugged design
- High long-term stability through built-in, maintenance-free refer ence gas cell, field calibration is unnecessary
- Real-time measurements
Moreover, the device provides warning and error messages in the following situations:
- Maintenance required with- Erroneous reference function- Bad signal quality
- Violation of a high or low threshold value for the measured vari able
- Transmitted amount of light violating a min. or max. value
