Pressure gauges are devices used to measure and display the pressure of a fluid (liquid or gas) within a system. They are essential tools in many industries to ensure safe and efficient operation by monitoring pressure levels.
Types of Pressure Gauges:
- Bourdon Tube Gauges: The most common type, using a coiled tube that straightens under pressure, moving a needle on a dial.
- Diaphragm Gauges: Use a diaphragm that deflects with pressure changes, suitable for low-pressure measurements.
- Capsule Gauges: Utilize two diaphragms welded together to measure very low pressures.
- Digital Pressure Gauges: Provide electronic pressure readings with digital displays, often more accurate and easier to read.
- Manometers: Measure pressure using a column of liquid, typically for low-pressure applications.
Selection Criteria:
- Pressure Range: The operational range of the gauge should match the expected pressure in the system.
- Accuracy: The precision required for the application.
- Size and Mounting: The physical dimensions and mounting style needed for the application.
- Environment: Consideration of the operating environment, including temperature, humidity, and exposure to corrosive substances.
- Type of Fluid: Compatibility with the fluid being measured (e.g., air, water, oil, corrosive fluids).
