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. 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 data apply to an optical path distance of 1 m in a nitrogen atmosphere under standard conditions 25 °C (or Tmin) and 1 013 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. Please 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) Up to 60 vol. % CO or up to 60 vol. % CO2. Higher CO or CO2 concentrations on request.
6) At high process temperatures, the use of an IR filter A5E00534668 is recommended for the CD 6 sensor (see page 2/xx).
