Abstract
Non-dispersive infrared sensors are widely used in industrial and scientific processes. Currently, there is no complete mathematical model of non-dispersive infrared sensors available which makes the development process of new sensor alterations a tedious task. The lack of a rigorous mathematical model requires the production of prototypes to quantify the impact of different sensor alterations on the sensor’s performance. This paper presents mathematical models for in commercially available nondispersive infrared sensors commonly used components: thermal infrared sources and thermopile detectors. The models are based on fundamental physical relations and are therefore easily adaptable to different thermal emitter and thermoelectric detector types. Furthermore, different measurement chamber geometries are simulated and their impact on sensor performance are analyzed.
