工业应用当中,管道在全长度范围内,内壁的质量和磨损直接影响其内径。为此,需要高精度,快速和可靠性高的测量数据评估管道内壁质量。例如,化学工业当中使用的管道,在使用的过程中进行磨损测量。需要将生产环节暂停下来,两套相互垂直90°的电容传感器,一次性将管道内壁测量完毕。


采用德国米铱公司提供的idiamCONTROL测量系统,使测量双蜗杆挤出机孔径的任务变得非常简单。该测量系统采用非接触式电容位移传感器,专门为测量塑料挤出机孔径而设计。

为了测量孔径,传感器组被塞入挤出机孔内,并很大限度地被推入通孔深处。测量系统采用两支反向安装的电容式位移传感器,测量挤出机通孔内壁的光滑程度。两支传感器测出的距离信息在控制器内部被换算成直径信息。可以通过旋转十字车轮40°,得到六组双蜗杆挤出机孔内径测量值。牵引测量传感器单元在被测孔内移动,测试单元会记录并存储直径测量结果和走过多长距离。可以通过RS232/USB端口,将测量数据传输给个人电脑,用于存档和图形化评测。测得的数据可以在整个通孔长度内展现为直径值,任何超过允许公差的偏差值都会被立刻显示出来。

An important criterion for the quality or the wear of tubes in industrial applications is the dimensional conformance of the internal diameter over the complete length. Where high demands are made on accuracy, a quick and reliable recording of the data must be ensured, because, for example, wear measurements must be carried out in the chemical industry on pipes which are already installed, i.e. with the plant shut down. Two pairs of sensors record two tracks offset by 90° in one measurement step. Through the calculation of the opposing sensor signals the absolute position of the Molch with respect to the center of the pipe is irrelevant - the roller guides are only used for coarse guidance.
