• Instrumentation Diagrams and Symbols (FG15C)


    Length: 1 day
    CEU Credits: 0.7
    Course Hours: 8:00 a.m.-4:00 p.m.


    This seminar presents the methodology for developing and applying instrument and control drawings and the ISA Standards available to assist in this effort. You will develop actual documents for a simple project to aid your understanding.

    You will be able to:

    • Define instrument and control systems, including: Process Flow Diagrams, Piping and Instrumentation Drawings (P&IDs), Instrument Lists, Specification Forms, Logic Diagrams, Location Plans, Installation Details, Loop Diagrams
    • Explain the type of information included on each document
    • Identify the sequence of document development for a typical project
    • Identify some process control devices and the symbols used to define them
    • Identify the ISA Standards available to assist you in developing and understanding instrument and control documents

    What You'll Cover:

    • Symbols: General Instrument or Function Symbols | Instrument Line Symbols | Function Blocks-Function Designations
    • ISA Standard Identification Letters: Typical Letter Combinations | Field or Local Instruments | More Primary Element Symbols | Typical Transmitters-Flow | Orifice Plates | Typical Transmitters-Level | Transmitters-Pressure and Temperature
    • Typical Controllers: Field Locations | Control Board Locations | Distributed Control System (DCS) | Computer | Programmable Logic Controller (PLC)
    • Control Valve Types: Actuator Action and Power Failure
    • Process Flow Diagram: Process Description | P&IDs and ISA Standards | Typical P&ID
    • Climatization: Instrument Numbering
    • Instrument List: Specification Forms | An ISA20 Specification Form
    • Logic Diagram: Binary Logic Diagrams for Process Operations | Motor Start Logic
    • Instrument Installation: Installation Detail
    • Loop Diagram: Types and Uses
    • Control Schemes: Feedback Loop | Radio Control | Cascade Control
    • Split Range

    Classroom/Laboratory Exercises:

    • Develop a diagram for a typical feedback loop
    • Compare symbols of instrument devices with their names
    • Use standards symbols to create partial instrument loops

    Includes ISA Standards:

    • ANSI/ISA-5.12009 - Instrumentation Symbols and Identification
    • ANSI/ISA-5.41991 - Instrument Loop Diagrams
    • ANSI/ISA-5.51985 - Graphic Symbols for Process Displays
    • ANSI/ISA-201981 - Specification Forms for Process Measurement and Control Instruments, Primary Elements, and Control Valves
    • ANSI/ISA5.06.01-2007 - Functional Requirements Documentation for Control Software Applications
