Instrumentation Symbols
Instrumentation symbols are essential elements in engineering drawings, particularly in the design and documentation of process control systems. These symbols are used on Piping and Instrumentation Diagrams (P&IDs), schematics, and installation diagrams to represent the control and measurement devices in the system. Understanding these symbols is crucial for anyone involved in the design, maintenance, or operation of a process control system.
Here’s a detailed look at the main categories and their uses:
Process Measurement Symbols
These symbols represent the various types of measurement devices used within the industry, such as temperature, pressure, flow, and level sensors. Common symbols include:
Flow Meter (F): Indicated by a circle with the letter “F.”
Temperature Sensor (T): Represented by a circle with the letter “T.”
Pressure Sensor (P): Shown as a circle with the letter “P.”
