微压与微差压是工业生产和科学实验中的重要参数。目前国内生产的微压和微差压变送器均属力平衡结构式仪表。而本文则介绍了采用微位移平衡原理的这类仪表,该表经现场运行证明其设计原理是可行的,并可在此基础上扩展到低差压、中差压和高差压,从而构成一个完整的产品系列。

Micro-pressure and micro-differential pressure is an important parameter in industrial production and scientific experiments. At present, the domestic production of micro-pressure and differential pressure transmitter are the balance of structural instrumentation. This article describes the use of micro-displacement balance principle of such instruments, the table by the field operation to prove its design principle is feasible, and can be extended to this on the basis of low differential pressure, the differential pressure and high differential pressure, thus constituting A complete product line.
