Non-Dispersive Infrared (NDIR)
How it works
Non-Dispersive Infrared (NDIR) sensors detect gas concentrations by measuring the absorption of infrared light at specific wavelengths. A light source emits infrared light through a gas sample. The target gas absorbs light at certain wavelengths, reducing the intensity detected by a sensor. By comparing this intensity with a reference wavelength, the gas concentration is determined. NDIR sensors are widely used for detecting gases like CO2, as they offer high accuracy and stability without requiring moving parts.
Advantages
-
High Accuracy: NDIR sensors provide precise gas concentration measurements, especially for gases like CO2 and methane.
-
Long-Term Stability: They maintain accuracy over time with minimal calibration needs.
-
Selective Measurement: NDIR targets specific gas wavelengths, reducing cross-sensitivity to other gases.
-
Durability: No moving parts make NDIR sensors robust and reliable in harsh environments.
-
Low Maintenance: Minimal wear and tear result in lower maintenance costs.
-
Fast Response: Quick detection and measurement of gas concentrations.
