Handling of the Gas Analysis System
order to guarantee a smooth and error free operation. Only expert personnel is allowed to clean the inside
of the casing and the gas-bearing lines and components so that the operational safety is not jeopardized.
CAUTION
The measuring point switch-over has a filter which ensures the gas exchange with the environment and
thus prevents a dangerous atmosphere inside. In the case of soiling, its function is impaired. Clean the
filter regularly.
6.1.2
Calibration
The calibration intervals depend on the sensors being used, the composition of the measuring gas and the
measuring interval. Normally, after the initial check of the system, one calibration per year is sufficient. If
you require a higher accuracy of results, or in case of heavy use, a calibration interval of 3–6 months is
recommended.
The calibration can be carried out directly on-site by Awite or an Awite partner. Please contact Awite for
further information.
6.1.3
Hydrogen sulphide filter
A hydrogen sulphide filter is implemented in devices that are fitted with a hydrogen sensor. For these gas
analysis systems, the colour of the filling needs to be checked. The unused filling material is black. A grey
or white colouring is an indication that the filter needs to be changed. Awite offers replacement filters or
refills. The replacement is done by AWITE in the course of the maintenance work. However, the filter has
to be replaced after 12 months at the latest and independent of the colouring.
6.1.4
Detonation Flame Arrester
A detonation flame arrester is not necessary as the distance of the tubes to the ignition sources is
correspondingly small. As the tubes are very small in diameter, they act as a deflagration flame arrester.
The type examination certificate is available from Awite on request.
6.1.5
Connecting Tubes
The gas analysis lines between the condensate traps and the gas analysis system are to be checked on
a regular basis for condensation discharges. There must be no condensate in the feeding tubes from the
condensate traps to the gas analysis system, as this can cause disruptions and defects in the gas analysis
system.
