3.2. Gas channel
Picture 8. The schematic diagram of the gas channel.
Labels used in the diagram:
The additional gas channel has been framed with violet.
V1 – ventilation valve of the main channel.
V2 – ventilation valve of the additional channel.
P1 – gas pump.
P2 – gas pump ventilating the additional channel.
S1...Sn – gas sensors of the main channel.
S+ – gas sensor of the additional channel.
F – Hydrophobic filter.
The elements in the direct contact with the examined gas create the gas system.
At first the gas sample passes through the dryer, where it is cooled (in order that the water
vapour condenses) and filtered. Afterwards, the sample is passed through the 3-way
solenoid valve and the pump to each of the gas sensors for analysis.
The maMoS analysers can be optionally equipped with an additional gas channel.
In such cases the gas sample is passed to the separate sensor (or sensors) through the
additional ventilation valve. The separate outlet has been installed in the additional gas
channel not to disturb the measurement process performed in the main channel. As a res-
ult the gas sample can be supplied to the separate sensor only when the concentration
