Appendix D: Carbon Dioxide Sensors

Appendix D describes the Eagle’s non-standard, infrared carbon dioxide (CO2) sensors. It also offers additional information for

calibrating and replacing CO2 sensors.

Specifications

Table 10 lists specifications for the carbon dioxide sensors. The alarm settings are user-adjustable (see “Updating the Alarm Point Settings” on page 32.)

Description

The Eagle uses an infrared sensor to detect carbon dioxide. The carbon dioxide sensor includes a dedicated amplifier with ZERO and SPAN controls. A bracket secures the sensor/amplifier assembly to the instrument case. A four-position connector plugs into the EC3 (channel 3) or EC4 (channel 4) socket on the analog PCB.

A carbon dioxide scrubber is mounted to the exterior front of Eagles that are factory-shipped with carbon dioxide sensors for the ranges 0 - 5,000 ppm, 0 - 10,000 ppm, and 0 - 5%.

NOTE: Eagles with a range of 0 - 20% and 0 - 50% CO2do not include a scrubber since the normal background of CO2 in air is negligible when compared to the full scale of these units.

This scrubber is for use when setting the carbon dioxide sensor’s zero reading only. Replace the scrubber when it turns from white to a violet color.

CAUTION: Do not connect the probe to the scrubber during normal operation or when setting the span reading during calibration.
