The following table lists the measuring conditions for standard applications. The listed values for the measuring range and detection limit (DL) are only approximate values. The exact values at the respective measuring point depend on the totality of all influencing variables and can be determined by Siemens for the specific case. Please note that the values for the detection limit and the maximum measuring range refer to a path length of 1 m. Longer path lengths will improve the detection limit, but not linearly. This is due to limiting effects such as dust load. The maximum applicable measuring ranges can only be used if permitted by the process conditions such as dust load.

1) All technical specifications apply to an optical path distance of 1 m in a nitrogen atmosphere under standard conditions 25 °C (or Tmin) and 1013 hPa. The effective detection limit, the measuring range and the accuracy can be influenced by process parameters such as pressure, temperature and gas composition. Not all combinations of maximum pressure and temperature can be realized with the minimum measuring ranges. If the process conditions deviate from the specifications of the standard applications, special applications are also possible on request. Complete the application questionnaire which can be found on the Internet at www.siemens.de/insitufragebogen.
2) At 0.3 m effective optical path length, average diameter of the dust particles: 15 µm, specific weight of the dust particles: 650 kg/m3
3) At least: Detection limit
4) Up to 200 °C, 5% above this
5) The accuracy corresponds to intrinsic uncertainty according to IEC 61207: 2 % of MV (0 ... 200°C); 2.5 % of MV (0 ... 400°C); at best 0.25 vol%*m.
6) At high process temperatures, the use of an IR filter A5E00534668 is recommended for the CD 6 sensor (see page 2/xx).
7) Suitable for use to measure NH3 according to the requirements of Directive 295/2009/EC "Implementing regulations on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (EURO VI)" from 18 June 2009 and its regulation for implementation of number 582/2011/EC from 25 May 2011 of the Commission of the European Union.
8) The device is also able to operate above 400 °C to 1 000 °C. Due to the decomposition of NH3 at higher temperatures, no specification can be given in these ranges.
