how ndir co2 sensor goes bad

Why NDIR? | Senseair

Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy. This is mostly because these sensors have no sensor burn-out, nor any sensor deterioration upon exposure to gases. Furthermore, the interference from other gases in the measurements is minimal to zero for NDIR sensors, depending on which gas is to be measured.

How Does an NDIR CO2 Sensor Work?

In our industry, many of us use the term "NDIR CO2 sensor", without thinking about what it stands for, or how NDIR sensors actually work. NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure CO2. An infrared (IR) lamp directs waves of light through a tube filled with air toward an IR light detector, which measures the amount of IR light ...

How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough. An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor …

How Do CO2 Sensors Work?

NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice. For CO2, the most commonly used wavelength is µm. This wavelength is not absorbed at all ...

11/01/2016· If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. If a bad oxygen sensor disrupts the air to fuel ratio mixture, or too much fuel is injected into the engine, your vehicle's gas mileage will be reduced. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust. If yourself filling up …

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift".
