Final answer:
The dial push/pull gauge is designed to measure pressure using a bellows-and-spring arrangement connected to a pointer on a calibrated scale.
Step-by-step explanation:
The dial push/pull gauge is designed to measure pressure. It is a type of mechanical pressure gauge that converts pressure into a force and displays it on a scale. The gauge typically uses a bellows-and-spring arrangement connected to a pointer on a calibrated scale.
Pressure can be measured using various devices, such as manometers or aneroid gauges. Manometers are U-shaped tubes filled with a fluid, and pressure is determined by the difference in fluid levels. Aneroid gauges use a flexible bellows that expands or contracts with pressure changes, which moves the pointer on the scale.
