In process engineering, there are often states in which the local distribution of fluids and solids and their temporal and spatial concentration represent dominant process‐relevant parameters. This article is dedicated to the monitoring of such processes, e.g., drying, moistening, and crystal structure formation, which requires the use of both space‐resolved and molecule‐specific measurement methods. A non‐contact measuring procedure is the near‐infrared (NIR) image analysis with an indium gallium arsenide (InGaAs) sensor. The application possibilities and the potential of this inline measurement method are presented and explained.

近红外图像分析作为监视过程活动的工具

在过程工程中，通常存在状态，其中流体和固体的局部分布及其时间和空间浓度代表了主要的过程相关参数。本文致力于监视此类过程，例如干燥，润湿和晶体结构形成，这需要使用空间分辨和分子特定的测量方法。非接触式测量过程是使用砷化铟镓（InGaAs）传感器进行近红外（NIR）图像分析。介绍并解释了这种在线测量方法的应用可能性和潜力。
