DDZ-S系列仪表包括变送、转换、显示、设定、辅助、调节控制、执行机构、数据链路、操作监控九大类仪表,共约90个基型品种一千多个规格。它是一套包括新型变送器、执行机构及配套仪表在内的两级智能仪表型综合控制系统,并可以与分散控制系统监控级联网,构成分散控制系统的一部分。S系列仪表在工业自动化领域具有广泛的用途,是我国近年来开发和生产的新一代成套工业自动化仪表。本文分4期连载介绍S系列仪表的总体设计思想和技术特点、S系列仪表的通用技术要求、S系列仪表的型号命名方法、S系列仅表的总体系统构成和基型品种一览表。
DDZ-S series instruments include nine types of instruments, including transmission, conversion, display, setting, auxiliary, regulation and control, implementing agencies, data links, operation monitoring, a total of about more than one thousand specifications of about 90 base types. It is a set of two-level intelligent instrument type integrated control system including new transmitter, actuator and supporting instrument, and can be cascaded with decentralized control system to form a part of decentralized control system. S series of instruments in the field of industrial automation has a wide range of uses, is China’s development and production in recent years a new generation of sets of industrial automation instruments. This article is divided into four series introduces the overall design ideas and technical characteristics of S series instruments, S series instrument general technical requirements, S series instrument model nomenclature, S series table only the overall system structure and base type list.
