美国博威量具公司最近研制成功一种可直接读数的电子测孔量具,使用时十分简单,不要求熟练的技术。量具由测量头和显示仪表两部分组成。工作时,使用相应尺寸的测量头,并在弹性承载器上装上相应尺寸范围的测量环。环上有三个带电的量柱,同被测内孔成三点接触。测量结果根据需要可以公制或英制单位在显示屏上读出。该电子测孔量具配有10个测量环和20个测量头,测孔尺寸范围:15—100毫米,如使用特殊附件可测量6—16毫米的小孔。测量精度为3微米,可重复性精度为2微米。
The United States Bowei Measuring Tool recently developed a direct reading electronic hole measuring tools, the use of very simple, does not require skilled technology. Gauge by the measuring head and display instrument composed of two parts. When working, use a measuring head of the appropriate size and attach a measuring ring of the appropriate size to the flexible carrier. Ring has three charged column, with the measured hole into three contact. Measurement results can be read out on the display in metric or imperial units as required. The electronic hole gauge with 10 measuring rings and 20 measuring head, hole size range: 15-100 mm, such as the use of special accessories can measure 6-16 mm holes. Measurement accuracy of 3 microns, repeatability of 2 microns.
