Pressure Measurement Bench
Model Number: H30
Investigate pressure and vacuum measurement using manometers and Bourdon gauges with practical calibration exercises.
Overview
A bench mounting apparatus to enable practical demonstrations and investigations into pressure and vacuum measurement techniques using manometers and Bourdon type gauges. Manometers and Bourdon gauges are fundamental pressure-measuring devices. They are intrinsic parts of more complex measuring instruments, such as pneumatic comparators and flow indicators. It is important therefore that students fully understand their operation, characteristics and principles of calibration. TecQuipment’s Pressure Measurement Bench enables students to fully investigate and compare the operation and characteristics of inclined and U-tube manometers, and Bourdon-type vacuum and pressure gauges. It also includes a separate Bourdon gauge with dead-weight calibration apparatus, enabling clear observation of the Bourdon tube mechanism.
Features
