2.1 General Description
Benefits
The in-situ gas analyzer LDS 6 is characterized by a high availability and unique analytical
selectivity, and by a broad scope of suitable applications. LDS 6 enables the measurement
of one or two gas components or – if desired – the gas temperature directly in the process:
● With high levels of dust load
● In hot, humid, corrosive, explosive, or toxic gases
● In applications showing strong varying gas compositions
● Under harsh environmental conditions at the measuring point
● Highly selective, i.e. mostly without cross-sensitivities
LDS 6 properties:
● Little installation effort
● Minimum maintenance requirements
● Extremely rugged design
● High long-term stability through built-in, maintenance-free reference gas cell, field
● Real-time measurements
Moreover, the instrument provides warning and failure messages upon:
● Need for maintenance
● Erroneous reference function
● Bad signal quality
● Exceeding of a lower or upper alarm level for the measured variable
● Transmitted amount of light exceeding an upper or lower limit
