Instrumentation (P&ID)

Instrumentation in the context of P&ID (Piping and Instrumentation Diagram) refers to the process of identifying, specifying, and representing the instruments and control devices used to monitor, control, and measure processes within industrial facilities, particularly in chemical plants, refineries, and manufacturing operations. P&IDs are essential engineering documents that visually represent the interconnection of process equipment and the instrumentation used to control and monitor them.
