标准摘要
[中文适用范围]： ，同时对关键参数的测量精度提出了具体要求。此外，还对仪器的安装、操作及维护等环节进行了规范，确保其在实际应用中的可靠性和一致性。 ***此介绍可能不准确，请注意参考原文。 [外文原描述]： This Aeronautical Recommended Practice covers two types of two unit Pressure Ratio Instruments each of which consist of a Transducer and an Indicator. The Transducer computes the ratio of two pressures and converts this ratio to a synchro electrical signal which is transmitted to the Indicator.Cross Reference: NACA1235
英文名称Pressure Ratio Instruments
