AP200 CO

O Atmospheric Profile System

Average power varies from 14 W above 30°C to 24 W at –30°C as

shown in FIGURE 4-23. This includes 2.0 W for the intake heaters (8

intake assemblies at 0.25 W each).

Pump Module

Pump type: Dual-head diaphragm pump with a

brushless DC motor

Mounting: Mounted in an insulated, temperature-

controlled box inside system enclosure

Control: Pumping speed is automatically controlled

to maintain the pump inlet pressure at the

set point

Maximum pumping speed: 9.0 liters per minute (LPM)

Pressure sensor range: 15.0 kPa to 115.0 kPa

Heater: 8.0 W, turns on/off at 2°C

Warm-up time: Approximately 50 minutes from –30°C to

2°C

Fan: 0.7 W (turns on at 50°C and off at 45°C)

Valve Manifold

Mounting: Mounted inside system enclosure

Inlets: Eight air sample inlets plus one inlet for

zero, one inlet for CO

span, and one inlet

for H

O span

Connections: 0.25-in Swagelok

Mass Flow Sensor: 0 to 1.0 standard liters per minute (SLPM)

Heater: 8.0 W, turns on/off at 5°C

Warm-up time: Approximately 20 minutes from –30°C to

4°C

Fan: 0.7 W; turns on at 45°C and off at 43°C
