Model 5398-21
Gas Sample Draw Panel
The Single Channel, Gas Sample Draw Panel (539821) 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 IT Series gas sensor modules for
Combustible or Toxic gases.
This gas sampling system uses a fast coop and
bypass type sampling method. An integral sample
pump draws the sample at a high flow rate to reduce
sample time lag. The sample is delivered to the sensor
up-stream from the pump to avoid negative pressure
conditions. 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. Each panel is a selfcontained 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 the
enclosure.
The Sample Draw Panels are intended for installation
in an indoor 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.
