  • Page 9: Technical Information

    General Description 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 analyzer unit.

  • Page 10: Alarms

    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: ●...

  • Page 13: Design

    2.2 Design Design The gas analyzer LDS 6 consists of a central unit and up to three in-situ sensors. The connection between the central unit and the sensors is established by a so-called hybrid cable, which contains optical fibers and copper wires. An additional cable connects the transmitter and receiver parts of the cross-duct sensor.

  • Page 19: Operating Principle

    2.3 Operating Principle Operating Principle LDS 6 is a gas analyzer employing single-line molecular absorption spectroscopy. A diode laser emits a beam of near-infrared light, which passes through the process gas and is detected by a receiver unit. The wavelength of the laser diode output is tuned to a gas- specific absorption line.

  • Page 20: Configuration Examples

    Figure 2-7 Typical transmitted light setup of LDS 6, in-situ A feature of the standard applications defined in the ordering data of the LDS 6 is that the typical process conditions are well-known and documented, and that the guaranteed measuring properties can be proven by reference installations. If you cannot find your application among the standard applications, please contact Siemens.

  • Page 21: Measurement Principle

    Measurement Principle Mode of operation The operation of LDS 6 is based on the fact that light propagating through a gas mixture will be absorbed according to Beer-Lambert's law at certain narrow wavelength bands. This is where the gases possess molecular transitions forming narrow absorption lines.
  • Page 22 In this case, the ratio of the absorbance of two characteristic lines of the same molecule measured at the same time in the same volume gives the actual temperature in the process gas. Typical measurable gases for LDS 6 are: ) for low and high pressure ● Oxygen (O ●...
  • Page 23 The optical damping increases at longer path lengths. Smaller particles also have a large influence on the optical damping. With a combination of high dust load, long path length and small particle size, the technical support at Siemens should be consulted. Temperature The temperature influence on the absorption line strength is compensated by a correction factor determined during calibration.
  • Page 24 2.5 Measurement Principle Pressure The gas pressure can affect the line shape of the molecular absorption line. LDS 6 uses a special algorithm to adapt the line shape. Additionally, an external pressure signal can be fed to the instrument to provide complete compensation for the pressure influence including the density effect.

  • Page 25: Installation Guidelines

    The device can be used in an industrial environment. Laser Safety All lasers used by LDS 6 are of class 1. The emitted laser light is in most cases invisible (near infrared) and the intensity is low enough so that the unprotected eye is not damaged under normal circumstances.
  • Page 26 The distance between the central unit and the sensors can be several hundred meters. The LDS 6 system is available in an Ex version and is then delivered with an approval for use in hazardous environments. The ATEX certificate is a system certificate and is only valid if LDS 6 is installed according to the instructions given in the certificate.
  • Page 27 An absolute condition for the approval is that the equipment is set up according to the drawing, ADM 3040 3050, please refer to the separate ATEX manual for LDS 6. The protection is as follows:...

  • Page 28: General Installation Information

    General Installation Information Mounting Conditions The central unit LDS 6 should be placed on a location which is dust-free and as free as possible from vibrations. The distance between the central unit and the measurement point, i.e. the sensor, may not exceed 1000 meters (3,280 ft) for the non ATEX version and 600 m (1,970 ft) for the ATEX version.

  • Page 29: Electrical Connections

    There are three kinds of cables used for the LDS 6 depending on the application: ● Hybrid cables for all types of systems except oxygen. These are installed between the LDS 6 and the transmitter sensor.
  • Page 30 ● A circuit-breaker shall be part of the installation. It must be provided in the immediate vicinity of the analyzer (see rating plate for loading capacity). It must also be labeled to correlate with the instrument. LDS 6 Operating Instructions, 01/2009, A5E00295894-05...
