The fabricated sensor was ...

Mini Lamps and T1 NDIR Sensor Lamps | ILT

+

The NDIR gas sensor needs an infrared source for the excitation of the gas molecules. Thermal radiators such as ILT''s Visible/IR lamps are often employed for this task. Their operating temperature should be as high as possible to obtain a large output intensity and detector signal. Glass envelope lamps operate at higher filament temperatures when compared to other filament or ceramic heating ...

How does an NDIR CO2 Sensor Work? |

+

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. The IR light detector measures the amount of IR light that ...

Signal conditioning for NDIR sensor Application note

+

The NDIR sensor is generally composed of a pulsed infrared source and a filter which hit the thermopile on the active junction. Under the effect of the radiation the active junction is heated. The reference junction is at the reference temperature and, in order to ensure a good stability, this reference junction is generally measured by a thermistor. In this manner a difference of temperature ...
