30-0954RK-200 Series Sample Draw Aspirator Adapter • 2
Figure 2: Component Location
The sample draw adapter consists of eleven major components (see Figure 2 ): the detector head (1
or 2), regulator, aspirator, detector adapter, detector chamber (1 or 2), flowmeter, calibration valve,
inlet/blowback valve, low flow switch, drain fault switch, and low flow and drain fault contact
housing.
Detector Head(s)
Each detector head provides a signal that can be used by a controller to indicate the sample gas
level. Any RKI S Series, S2 Series, M2, or direct connect detector head can be used with the
sample drawing adapter plate. Figure 2 above shows the approximate location of the two detector
heads. Please see the detector head operator’s manual of the detector head(s) in your system for a
complete description of the detector head(s).
