Introduction & Overview

Introduction & Overview

Measurement Principle

The SBA-5 OEM CO2 Analyzer is a non-dispersive, infrared gas analyzer that features an “Auto­Zero” facility. Using infrared gas analysis techniques, we can readily determine CO
Dioxide) concentrations to within a few ppm and instantaneous measurements are possible.
Gases with di-atomic molecules such as CO

, one region of strong absorption is 4.26 microns. A source (IR source) emitting strongly at

CO

2

strongly absorbs photons in the infrared range. For

2

this wavelength is a light bulb. If this is positioned at one end of a tube and at the other end is a
sensor that is sensitive to photons at 4.26 microns, we have a simple infrared gas analyzer. As

is passed down the sample cell, it absorbs some of the infrared and the sensor reading

CO

2

decreases. The “Auto-Zero” feature, which occurs at regular intervals, allows for fast warm-up,
adaptation to changing ambient conditions and excellent stability of the CO

signal. The action of

2

auto-zeroing minimizes the effects on span (gas sensitivity) of sample cell contamination, source
aging, changes in detector sensitivity and changes in pre-amplifier gain. By default and after
system warm-up, the SBA-5 will perform “Auto-Zeros” every 20 minutes. The “Auto-Zero” interval
can be changed by the user if required up to a maximum of 10,000 minutes. PP Systems highly

recommends that the SBA-5 performs frequent “Auto-Zeros” to ensure accuracy and
reliability of data.

The SBA-5 features automatic temperature and pressure compensation.
The SBA-5 is supplied as a calibrated CO

optical bench (to a specified range) fitted to an FR4

2

type printed circuit board (PCB). All components are located on the board.

Powering up the SBA-5

The SBA-5 requires a 6-18V DC input to power up the analyzer. Power can be applied to 3
different connectors on the SBA-5 board (CN2, CN3 or CN4). See sections below for appropriate
connections.

Operation

Once the SBA-5 is connected to a proper power supply and immediately after it is powered up,
there is a short pause and then the IR source lamp starts to flash. If the RS-232 or USB line is
connected to a PC running a terminal program (i.e. Hyperterminal on older PC’s and
HyperAccess on more recent PC’s), the following information is transmitted:
