![Page 1: The Piping and Instrumentation Diagram Schematic of a control system –more detailed than process flow diagram –does not include values of parameters Used.](https://reader033.fdocuments.net/reader033/viewer/2022052701/56649d435503460f94a1eb99/html5/thumbnails/1.jpg)
The Piping and Instrumentation Diagram
•Schematic of a control system–more detailed than process flow diagram–does not include values of parameters
•Used in conjunction with flow diagram parameters to produce a completely working process

Line Types
• Connect different units in controlled system

Identification Letters• First letter represents parameter to be controlled, not the
action used to control that parameter• Second letter is the type of control device

Actuator Symbols
• Used to activate process control equipment

Transmitters• Sensors used to measure parameters
• Send information to actuators to control process
• Location depends on application
• Set points, indicated by dots, show specific location
