Description:
The Pressure Measurement Bench is a comprehensive experimental setup designed for the study of pressure measurement techniques using various instruments, including inclined and U-tube manometers, and Bourdon-type vacuum and pressure gauges. The apparatus provides a practical platform for students and professionals to explore the calibration, comparison, and accurate measurement of pressure and vacuum.
Key Features:
• Versatile Pressure Measurement: Enables practical investigations using inclined and U-tube manometers, along with Bourdon-type vacuum and pressure gauges.
• Instant Comparison of Measurement Methods: Facilitates immediate comparison between different pressure measurement techniques.
• Accurate Pressure and Vacuum Control: Allows precise pressure and vacuum control through the fine adjustment of a syringe assembly.
• Bourdon Gauge Calibration: Includes a separate Bourdon gauge with dead-weight calibration apparatus and a visible Bourdon tube mechanism for better understanding.
• Self-contained Bench-top Apparatus: Fully self-contained, suitable for easy setup and use in both group demonstrations and individual student experiments.

Experimental Capabilities:
• Pressure Measurement Comparison: Compare pressure measurement techniques using both manometers and Bourdon gauges.
• Pressure Gauge Calibration: Perform calibration of a pressure gauge for accuracy.
• Gauge Error Determination: Determine the gauge errors as a function of true pressure.
