摘　　要：提出了开关量两线制的概念、原理、规范,说明了机械式开关两线制与电子开关两线制的区别,从模拟量两线制基理出发,在理论上创立了开关量两线制,并为实现开关电子化和仪表的全范围两线制和通用化提供了基础。本技术填补了开关量两线制的技术空白,验证了不漂移、不故障,可监控等全球独家技术品质。本文主要描述了电子压力开关两线如何供电,如何工作,两线制如何实现比机械式压力开关更强,应用的业绩如何等一系列研究与应用的问题。This paper puts forward the concept, principle and specification of two-wire system of switch quantity, explains the difference between two-wire system of mechanical switch and electronic switch. It also provides the basis for realizing the elec- tronic switch and the wide-range two-wire system of the instrument. This technology fills up the technical gap of two-wire system of switch quantity, and verifies the global exclusive technical quality such as no drift, no fault, monitorable and so on.This paper mainly describes how to supply power to two lines of electronic pressure switch? How to work? How to realize the two-wire system? Why is it more reliable than mechanical pressure switches? how the performance of the application and a series of research and application problems.
