ISA has published a new update of its most widely used standard, the internationally recognized ANSI/ISA-5.1, Instrumentation and Control Symbols and Identification. ISA-5.1 establishes a uniform means of depicting and identifying instrumentation and control functions used for measurement, monitoring and control in the process industries.
The 2024 revision of this standard changed the title from Instrumentation Symbols and Identification to Instrumentation and Control Symbols and Identification to emphasize that symbols for control are included. In addition, improvements have been made to the standards' readability, as well as the addition of new symbols, recognition of new automation technology, reference sections and the loop instrument diagrams symbol table.
