摘要
本文介绍扬压力传感器从传压膜片的结构设计、差动转换方式、取同一电路变换的差值信号、以及可信赖的双重密封结构等多方面措施来提高传感器的零点稳定性,为扬压力自动观测系统提供可靠的一次信息源-高稳定扬压力传感器。
This paper introduces the measures taken to raise the zero-point stability of the uplift pressure sensor, including the measures in the design of the membrane structure, the mode of differential change-over, the double sealing structure, etc. The present GY-type uplift pressure sensor can provide the automatic uplift pressure observation system with a reliable information source.
