Pratt&Whitney Measuring Systems Operation公司提供的Supermike 直接读数外径仪已有几年了。目前,该公司的工程师们又发展了一种同类型的Supermike 直接读数内径仪。这种新量仪提供了一种直接测量内尺寸的万能方法,它不需要有单独保证和确定每种尺寸的校对块就能测定和显示内尺寸。P&W 工程师们深信,它在内尺寸测量的先进水平上是仅有的一种量仪,这种量仪的精度为±0.000050″,并具有直接调整的数字组件,其范围为0～1.00000″精度的基础。Supermike 内径仪由5部分组成,第一部分为铸铁基座和
The Supermike Direct Reading OD Meter from Pratt & Whitney Measuring Systems Operation has been around for years. Currently, the company’s engineers have developed a similar type of Supermike direct reading bore diameter meter. This new meter provides a versatile method of directly measuring the inner dimensions without the need for a separate assurance and confirmation of proofing blocks of each size to measure and display the inner dimensions. P & W engineers are convinced that it is the only gauge available at the advanced level of internal dimensioning with a precision of ± 0.000050 “and a directly adjustable digital component in the range of 0 to 1.00000” Foundation. Supermike diameter instrument consists of 5 parts, the first part of the cast iron base and
