Description:
Texas Analytical Controls is proud to announce its latest and most reliable CO2 Analyzer; Model 313XP. The Model 313 Series uses the proven non-dispersive infrared (NDIR) principle to detect and monitor the presence of CO2. The Model 313 Series can be ordered in the following ranges:
- 0-3000ppm
- 0-2% vol CO2
- 0-30% vol CO2
- 0-100% vol CO2
This non-poisoning sensing technique relies on the target gas having a unique, well-defined absorption signature. This is used to identify the presence of the target gas (i.e. CO2) and it is highly gas specific. Using a suitable infrared source, an analysis of the optical absorption through the gas allows the concentration of the target gas to be determined. The durable, non-corrosive polyacetal construction is resistant to most weak acids, bases and solvents, with no damage after prolonged exposure to H2S. By using IR sensors operators benefit from:
- Reliability, low maintenance
- Fail safe operation
- No moving parts.
Operation:
A long-life tungsten filament lamp is used as a broadband infrared thermal source directed at the detectors. The lamp supply voltage pulse rate is 4 Hz at 50% duty. By pulsing the source, background interference effects may also be reduced or eliminated.
Two infrared detectors are used. The filter fitted to the "active" detector is transparent to the strong fundamental absorption band of CO2. This allows a short optical path length to be used while maintaining satisfactory resolution. The output amplitude from the active detector is then reduced as the optical radiation is attenuated on passing through the CO2 gas. The second "reference" detector is made insensitive to this change by using a different filter. By taking the ratio of the two detector signals, the user can discriminate between the signal reduction due to the target gas, and that due to ambient physical variations.
