Study Notes
Pressure Units and Conversions
- 1 Bar is equivalent to approximately 14.5038 psi (pounds per square inch).
- 1 Bar converts to 100 kPa (kilopascals), making it a standard pressure measurement.
- There is a duplicate mention of the conversion from 1 Bar to psi and kPa; both conversions reinforce the relationships between these common units.
Absolute Pressure Scale
- The zero reference point in the Absolute pressure scale is absolute zero pressure, which is a perfect vacuum (0 psi or 0 Bar).
Pressure Sensor Terminology
- LRV stands for Lower Range Value, indicating the minimum pressure that a sensor can accurately measure.
- URV stands for Upper Range Value, representing the maximum pressure limit of a pressure sensor.
Pressure Sensor Types
- Bourdon Tube pressure sensors are commonly used for measuring higher pressures and provide mechanical measurement through the deformation of a tube.
- Bellows-type pressure sensors use cylindrical bellows that expand or contract based on pressure changes, allowing for precise measurements especially in lower pressure ranges.
