    Description Overview SITRANS SL is a diode laser gas analyzer with a measuring principle based on the specific light absorption of different gas components. SITRANS SL is suitable for fast, non-contact measurement of gas concentrations in process or flue gases. An analyzer consisting of transmitter and receiver unit (sensors) is used for each measuring point.

    Typical spectral bandwidth of an absorption line compared to the bandwidth of the laser light. The field design of the SITRANS SL in-situ gas analyzer consists of a transmitter unit and a receiver unit. The light which is not absorbed by the sample is detected in the receiver. The concentration of the gas component is determined from the absorption.

The standard applications listed in the ordering data for the SITRANS SL are distinguished in that the typical process conditions are adequately well-known and documented. If you cannot find your application among the standard applications, please contact Siemens AG.

  • Page 22: Influences On The Measurement

    The optical damping increases exponentially at longer path lengths. Smaller particles also have a very large influence on the optical damping. With high dust load, long path length and small particle size, the technical support at Siemens AG should be consulted.
  • Page 23 Adjustment of the sensor pair The process flanges of the SITRANS SL must be correctly aligned so that the laser beam generated by the transmitter hits the photodetector in the receiver unit. This is guaranteed in that the transmitter and receiver units have a curved surface integrated in the flanges. The adjustment is carried out by shifting the flanges on these surfaces, through which the symmetry axis is aligned.

For details see Service and support (Page 201) ①...
  • Page 40 Installing 4.2 Mounting At installation of the SITRANS SL, the laser and the photo-detector have to be aligned to the optical axis of the sensor pair. Note that each sensor has an optical axis of its own which is its axis of symmetry. In addition the sensor body is at an angle to this axis. The reason for this is that the laser beam passes a wedged window before exiting.

    A latent defect, on the other hand, is more difficult to identify. It means that the device has only been partially degraded from exposure to an ESD event. Latent defects are extremely difficult to prove or detect using current technology, especially after the device is assembled into a finished product.

    Verification Sheets Instrument Verification Albeit the SITRANS SL provides a high long-term stability due to the built-in, maintenance- free reference gas cell, a verification should be carried out at regular intervals. Details of that procedure are described in section 9.1. (Page 149) This procedure should be documented using the appropriate verification sheet provided later in this section.

Intel-based computers, for example, save the data differently from the Siemens controllers (S7), namely, in reverse sequence. The byte sequence from Intel, termed Little Endian, is therefore the reverse S7 byte sequence, Big Endian.
