5.3 Gas connections
Sample gas line
For the gas supply and discharge lines, there is one directly heated inlet (sample) and one
directly heated outlet each. Separately heated sample gas supply lines each require their
own power supply and temperature regulation.
The hexagon of the bulkhead unions is seated in a anti-rotation lock. When tightening the
union nuts on the unions, always ensure that you counter-hold properly with a suitable open-
end wrench. Otherwise there is a danger that the gas path will leak.
FIDAMAT 6-E: The sample gas is drawn in by a diaphragm pump with a capacity of
approximately 1 l/min. Ensure that the sample gas is at atmospheric pressure. However, the
device can also be operated at a constant overpressure or underpressure of up to 100 hPA.
FIDAMAT 6-G: The sample gas is supplied unheated by a solenoid valve.
