SQ251 FLK Gas Sampling Probe
2 Installation
2.1 Gas sampling probe
The gas-sampling probe can basically be installed according to requirements, but the following possible methods
should be considered.
• On a manual retraction device.
• On an automatic retraction device.
It should be ensured however that the probe is mounted at an angle of about 5° sloping down to the probe tip.
This prevents the formation of air bubbles in the probe.
A fixed installation of the probe is not recommended.
• Because if the cooling fails (also with power failure) and with cessation of the flow, dangerous coolant
overheating may occur.
• The weight of the probe is about 130 kg.
• Excessive material deposits on the cooling pipe lead to increased mechanical loading and to excessive
cooling of the cooling medium. When the cooling medium cools below the acid dew point, this leads to
blockage of the sampling pipe. The probe would then have to be removed for cleaning.
With an installation with a manual retraction device, appropriate mounting holes for the probe must be provided on
the carriage together with mounting for the valve combination and the dust removal filter.
Note:
Installation plans must be requested from the relevant SIEMENS subsidiary.
Mountings are provided for the probe, valve combination and dust removal filter for installation with an automatic
retraction device.
After mounting the retraction device, the probe is placed on the carriage and fastened to it (see Figure 3).
See the separate operating manual for the installation of the retraction device.
