Intended use
The Dräger SAM 3100/SAM 3200 is an aspirator system for
continual intake of gas/air mixtures for a gas transmitter
(SAM 3100) or for two gas transmitters (SAM 3200), in order
to carry out measurements of toxic and/or explosive
substances in hard-to-access places.
In the event of insufficient process overpressure, a partial flow
of the process gas is siphoned off from the process using
a gas sampling pump with electric drive, or alternatively using
an ejector.
In order to separate solid particles from the gas flow,
the gas is passed across a filter.
The sample gas is passed to the flow meter with ring
initiator (for flow monitoring) via a 3/2-way spherical valve
(option for simplified feeding of test gas) and then flows into
the sample chamber of the sensor or sensors.
The air is either discharged to atmosphere or fed back
to the intake point by means of the air outlet on
the transmitter.
WARNING
!
During installation without return feed for the sample
gas back to the intake point, the sample gas should be
guided to a vent or outside. Risk of poisoning or
explosion! The return feed must not be pressurised.
