Function: Measures the force exerted by a gas or liquid against a vessel's walls. It quantifies this force in various units such as pounds per square inch (psi), bar, pascals (Pa), or other pressure units.
Types: There are different types of pressure meters designed for specific purposes, including absolute pressure gauges, differential pressure gauges, and gauge pressure gauges.
Applications: Used across various industries including automotive, HVAC systems, oil and gas, manufacturing, medical equipment, and many more where monitoring and controlling pressure is crucial.
Mechanism: Operates by the expansion or displacement of a diaphragm, Bourdon tube, or another mechanism in response to the pressure being measured. This movement is then translated into a pressure reading on the meter's display.
Accuracy: Comes in different accuracies and pressure ranges depending on the specific application. Some are very precise and can measure extremely low pressures, while others are built for high-pressure environments.
