Gas Sample Draw Panels
Gas Sample Draw Panel (5398-21) provides an easy to
use method of drawing an air sample from a remote, or
hostile area to a more convenient location for analysis.
The Sample Draw Panel can use gas sensor modules
for Combustible or Toxic gases, either the Sentry style
modules or the Analog (4-20 mA output) modules. It
can use gas sensor modules for Combustible or Toxic
gases.
The integral sample pump to draw the sample at a high
flow rate to reduce sample time. The sample is delivered
to the sensor up-stream from the pump to avoid negative
pressure conditions. A bypass line exhausts excess
sample volume to avoid high flow rates across the sensor.
Each panel is a self-contained system with the pump,
flow indication, valves to control sample draw and
calibration gas delivery, and the gas detection sensor
and transmitter (priced separately) all housed in an
enclosure. The flow systems design will deliver the
sample to the sensor with minimal pressure affecting
the sensor as the excess flow and pressure are bled off
via the bypass flowmeter.
Model 5398-21
The Sample Draw Panels are intended for installation in
an area, which is accessible, by the user for periodic
routine inspection and calibration. The panel requires
120 VAC input and provides local visual as well as
remote indication of pump and flow status.
