ISA instrumentation symbols software for use with Visio
ANSI/ISA-5.1-2009, Instrumentation Symbols and Identification, is one of ISA's most widely used standards. It establishes a uniform means of depicting and identifying instruments or devices and their inherent functions, instrumentation systems and functions, and application software functions used for measurement, monitoring, and control. The standard presents a designation system that includes identification schemes and graphic symbols.
A new ISA software product is available for using the symbols within the Microsoft Visio software platform. It has graphic symbols for engineering design and drawing layout for a variety of instrumentation-related activities, including:
- Piping and instrument diagrams
- Process flow diagrams
- Logic diagram development
- Electrical schematic layouts
- Functional block diagrams
- Instrument loop diagrams
The software features a shape and stencil configuration for ease of symbol selection by symbol group. It also has preassigned shape data prompts for assigning ISA-style tag numbers (prefix, functional ID, loop number, suffix) to instrument bubbles, and it has instrument bubbles formatted to accommodate long tag numbers and legend tables formatted for engineering legend sheet layout.
The new software complements a previous version intended for use within the Autodesk AutoCAD software platform.
