How does an NDIR CO2 Sensor Work? |

How does an NDIR CO2 Sensor Work? January 05, 2021 NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

OSA | Widely-tunable mid-infrared fiber-coupled quartz ...

A compact widely-tunable fiber-coupled sensor for trace gas detection of hydrogen sulfide (H2S) in the mid infrared is reported. The sensor is based on an external-cavity quantum cascade laser (EC-QCL) tunable between and μm wavelengths coupled into a single-mode hollow-core waveguide. Quartz-enhanced photoacoustic spectroscopy has been selected as detecting technique.

Thermal Conductivity versus Infrared CO2 Sensors | Blog ...

Most infrared CO 2 sensors use a miniature incandescent light bulb as the infrared source (Figure 6), which are not the ideal source for sensors. Firstly, the initial light intensity varies greatly between units, making deployment challenging. Secondly, they suffer from inherent instability: tungsten evaporates from the thin filament and adheres to the glass surfaces, blackening the bulb walls ...

The Correct Material for Infrared (IR) Applications

Infrared (IR) radiation is characterized by wavelengths ranging from -1000μm (750 - 1000000nm). Due to limitations on detector range, IR radiation is often divided into three smaller regions: - 3μm, 3 - 30μm, and 30 - 1000μm – defined as near-infrared (NIR), mid-wave infrared (MWIR), and far-infrared (FIR), respectively (Figure 1). Infrared products are used extensively in a ...

A near-IR CO trace gas sensor based on quartz-enhanced photoacoustic spectroscopy (QEPAS) is evaluated using humidified nitrogen samples. Relaxation processes in the CO-N2-H2O system are investigated. A simple kinetic model is used to predict the sensor performance at different gas pressures. The results show that CO has a ~3 and ~5 times slower relaxation time constant than CH4 and HCN ...
