Process and instrumentation diagram

Process and instrumentation diagram

Process and instrumentation diagrams are a family of functional one-line diagrams showing hull, mechanical and electrical (HM&E) systems like piping, and cable block diagrams. Abbreviated as P&ID, they show the interconnection of process equipment and the instrumentation used to control the process. They are the primary schematic drawings used for laying out a process control installation in a factory or plant. In the process industry, a standard set of symbols may be used to prepare drawings of processes, for instance the instrument symbols used may be based on Instrumentation, Systems, and Automation Society (ISA) Standard S5.1.
