instrumentation and control system, a solid understanding of the symbols and terminology used to depict the process system is required. This course will use the ISA/ANSI standards shown in this section for all process illustrations. ISA (International Society of Automation) / ANSI (American National Standards Institute). Instrument line symbols
Double lines indicate the instrument is at an auxiliary location away from the process Symbols with a single dashed line indicate the instrument is located behind a panel and not easily accessible.

The International Society of Automation (ISA), formerly known as The Instrumentation, Systems, and Automation Society, is a nonprofit technical society for engineers, technicians, businesspeople, educators and students, who work, study or are interested in automation and pursuits related to it, such as was originally known as the Instrument Society of America.
Aug 01, 2000· Being able to understand instrumentation symbols appearing on diagrams means understanding ANSI/ISA''s (R 1992) Instrumentation symbols and identification standard. that defines how each symbol is constructed using graphical elements, alpha and numeric identification codes, abbreviations, function blocks, and connecting lines.
The symbols defined in are intended to supplement those of and to provide a cohesive integration of graphic symbology and common industry usage of flow diagrams. and are drafting standards which govern the depiction of process and instrumentation symbols for drawings and other printed documents.

It is common to make letter combinations in PID diagrams according ANSI/ISA (R 1992) "Instrumentation symbols and identification". In addition to the letter combination a succeeding number as a unique identification of the actual instrument is commonly used.

May 02, 2018· However, ISA instrumentation symbols go beyond that. They also tell you where the instruments are installed. In some of the shapes, you might see lines crossing them. If you don''t see a line, then that device is installed locally in the field. If you see a solid line, you''ll find the instrument on a main panel or screen.

Loop diagrams are fairly constrained in their layout as per the ISA standard. Field instruments are always placed on the lefthand side, while controlpanel or controlroom instruments must be located on the righthand side. Text describing instrument tags, ranges, and notes are always placed on the bottom.
