What does the symbol displayed typically represent in a schematic?

In a schematic, the symbol typically representing a gauge is designed to depict an instrument that monitors and displays various parameters such as pressure, temperature, or flow rate within a system. Gauges are crucial for ensuring the system operates within safe and efficient parameters, providing visual feedback that can be easily interpreted by operators.

The gauge symbol often features a circular or rounded shape with markings to indicate measurement values, and sometimes includes a pointer or needle to reflect the current reading. This visual representation is distinct from symbols for other components, which have their own specific designs influenced by their functions. Understanding the gauge’s role within a schematic enhances the overall comprehension of a system's monitoring and operational capabilities.
