Study Notes
Pressure Measurement Devices
- A manometer is commonly used for mechanical pressure measurement and display. It utilizes liquid columns to indicate pressure levels.
Vacuum Gauge
- A vacuum gauge measures pressure in a vacuum system. It indicates how much the pressure is below the atmospheric pressure.
Gauge Pressure Zero Point
- The zero point for gauge pressure readings is set at atmospheric pressure. This means gauge pressure readings reflect the pressure above or below the ambient atmospheric pressure.
Units of Pressure
- Pressure is typically measured in units such as Pascals (Pa), atmospheres (atm), bar, and psi (pounds per square inch). Each unit has specific applications depending on the context.
Compound Gauge Purpose
- A compound gauge is designed to measure both positive and negative pressures. It provides readings above and below atmospheric pressure, allowing for more versatile applications in various systems.
