The following table lists the measuring conditions for standard applications. The listed values for the measuring range and detection limit 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.

Reference table: Standard applications. The specified pressures are absolute.

DL = detection limit

¹⁾ The specification applies at 20 °C and 1013 hPa in a nitrogen atmosphere. In rare cases, a deviating process gas matrix or process conditions can have a negative effect on performance. Please contact Siemens to determine the exact performance under your process conditions.

²⁾ With 0.3 m effective optical path length

Average diameter of the dust particles: 15 µm

Specific weight of the dust particles: 650 kg/m³

The influence of dust load is extremely complex, and depends on the path length and particle size. The optical attenuation increases exponentially at longer path lengths. Smaller particles also have a very large influence on the optical attenuation. With high dust load, long path length and small particle size, the technical support at Siemens should be consulted.

³⁾ Referred to measuring range.

With stable or externally measured and software-compensated process gas temperature and pressure conditions.

Special applications

	In addition to the standard applications, special applications are available upon request. If the process conditions deviate from the specifications of the standard applications, special applications are also possible on request.
