There are a multitude of technologies used to assess and control the quality of gases used in carburizing processes. These range from high-technology optical methods, such as nondispersive infrared, to relatively low-tech dewpoint measurements.
The purpose of this review is to determine the baseline sensitivity of each sensor technology gas well as the fidelity of the sensor output over a wide range of gas compositions.
As well as serving to extend base understanding of sensor detection mechanisms, this study can serve to better match a gas range or composition with an optimal sensor technology
