“化工过程检测、控制系统设计符号统一规定”(CD50Al—80)适用于化工自控工程设计。又如,“化工自控施工图设计深度规定”等,用以表示过程检测、控制(或调节)系统所采用的工业仪表。在自控工程设计工作中应当按照“统一规定”的内容进行设计。本讲座仅提取其主要内容进行介绍,如与“统一规定”不符之处,请按照“统一规
“Chemical process testing, control system design symbols unified regulations” (CD50Al-80) for chemical engineering design. In another example, “Chemical Control Construction Design Depth Regulations” and so on, used to indicate the process of detection, control (or regulation) system used by industrial instrumentation. In the self-control project design work should be in accordance with the “uniform provisions” of the content of the design. This lecture only extracts its main content for introduction, such as inconsistency with the “uniform rules”, please follow the "unified rules
