LDS 6

LDS6는 IN-SITU Type의 Laser를 광원으로 사용하는 NIR분석기로서 Sample 을 sampling / conditioning하지 않고 직접 sensor를 process에 취부하여 가스를 분석하는 분석기 입니다. 이는 빠른 응답속도와 방해가스로부터 측정에 방해를 받지 않습니다. 주로 탈질 설비의 촉매 후단의 NH3 SLIP 감시용으로 쓰이며 그 외에 HCL, NH3, O2, CO/CO2등 수분에 아주 민감한 가스를 안정적으로 측정 가능합니다.

■ Overview

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 concentrations or temperatures in process or flue gases.

One or two signals from up to three measuring points are processed simultaneously by one central unit by using fiber-optic cables.

The sensors are designed for operation under harsh environmental conditions and contain a minimum of electrical components. By connecting an by pass stream to a separate flow cell, measurement can also be carried out extractively instead of in-situ

■ Benefits

The in-situ gas analyzer LDS 6 is characterized by a high operational availability and unique analytic selectivity, and by a broad scope of suitable applications. LDS 6 enables the measurement of one or two gas components or the gas temperature directly in the process:

- With high levels of dust load (up to 100g/Nm3)

- 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 interfaces.

LDS 6 properties:

- Little installation effort

- Minimum maintenance requirements

- High degree of ruggedness

- High long-term stability through built-in, maintenance-free reference gas cell, field calibration is unnecessary

- Real-time measurements

Moreover, the instrument provides warning and failure messages upon:

- Need for maintenance

- Erroneous self calibration

- Bad signal quality

- Violation of a lower or upper alarm level for the measured variable

- Transmitted amount of light violating an upper or lower limit.
