摘要

作者回顾了校准低差(25-300英寸)的方法。H2 O) dp变送器在高(高达3000 psig)静压下。描述了各种测试方法，并讨论了它们的优点。包括使用一个或多个自重测试仪(气体或液体)和使用高压水银压力计作为标准。对5种不同结构的dp发射机进行了测试，并报告了它们的静态跨移性能。

Differential Pressure Transmitters, Span-Shift Errors With Static Pressure

The author reviews methods of calibrating low-differential (25–300 in. H2 O) D.P. transmitters at high (up to 3000 psig) static pressure. Various test methods are described along with discussion of their merits. Included are use of one or more deadweight testers (gas or liquid) and use of a high-pressure mercury manometer as a standard. Five D.P. transmitters of different construction are tested and their static span-shift performance reported.
