美国俄亥俄州的埃莉奥特(Elliott)联合工程应用技术公司研制成功一种Elliott 抛光表面分析仪,这是一种导电性材料表面粗糙度的电容式测量仪,它也可以测量大多数半导电材料的表面。该分析仪拥有一只测量粗糙度值的液晶条线图显示器。它使用一只传感器挤压测量表面,由传感器评定该区域的平均表面精度。这种非擦伤式传感器由柔性的弹性减震垫自动控制,使传感器沿表面轮廓定位。经专门定标的分析仪可测量抛光零件的表面粗糙 Elliott, Ohio, United Engineering Co., Ltd. has successfully developed a joint Elliott polished surface analyzer, which is a capacitive surface roughness measurement of conductive materials, it can also measure most of the semi-conductive The surface of the material. The analyzer has a liquid crystal bar graph display that measures roughness values. It uses a sensor to squeeze the measuring surface, the sensor to assess the average surface accuracy of the region. This non-chafing sensor is automatically controlled by a flexible, elastomeric cushion that positions the sensor along the surface profile. Specially calibrated analyzers measure the surface roughness of polished parts
