Introduction:
Non-dispersive Infrared (NDIR) gas sensors have become an increasingly important part of various industrial and commercial applications, due to their ability to detect and respond to a wide range of gas types and浓度 at a high sensitivity and accuracy. In this article, we will explore the principles of non-dispersive NDIR gas sensors, their advantages, and applications.
Principles of Non-dispersive Infrared Gas Sensors:
Non-dispersive NDIR gas sensors work by detecting the change in energy due to the interaction of a gas with a particular frequency of light. The gas molecules absorb the light energy, and the amount of energy absorbed is proportional to the number of molecules present. The sensor then发
