通过修正定向误差无接触地确定料幅厚度的方法和装置
摘要：
本发明涉及一种用于借助传感器装置无接触地确定料幅，尤其是纤维料幅的厚度的方法，所述传感器装置包括至少两个光学测量单元，料幅能够在这两个光学测量单元之间导引通过，并且这两个光学测量单元在其朝向料幅的一侧分别具有试验板，其中，通过布置在料幅相互对置侧的光学测量单元分别确定该光学测量单元与料幅的距离，并且借助评估单元由所确定的光学测量单元与料幅之间的距离以及所述布置在料幅相互对置侧的光学测量单元之间的距离确定料幅的厚度，其特征在于，所述布置在料幅相互对置侧的光学测量单元分别配设有多个彼此间隔的光学传感器，并且借助评估单元根据由光学传感器得到的测量值确定试验板相对于料幅的倾斜角和/或所述布置在料幅相互对置侧的光学测量单元之间或其试验板之间的错移。
摘要（英）：

Disclosed is a method for the contactless determination of the thickness of a web of material, especially a web of fibrous material, by means of a sensor array comprising at least two optical measurement units, between which the web can be guided. Each of the optical measurement units includes a measurement plate on the side facing the web. The optical measurement units, which are arranged on opposite sides of the web, are used to measure the distance of the measurement units from the web, and an evaluation unit is used to determine the thickness of the web from the determined distances between the optical measurement units and the web and the distance between the optical measurement units arranged on opposite sides of the web. The disclosed method is characterized in that multiple optical sensors which are disposed at a distance from each other are associated with the optical measurement units arranged on opposite sides of the web, and in that the evaluation unit is used to determine the angle of inclination of the measurement plates relative to the web and/or an offset between the optical measurement units arranged on opposite sides of the web or between the measurement plates of said units on the basis of the measured values obtained from the optical sensors.
