Diaphragm gauge

A diaphragm gauge measures pressure by using a flexible metal or rubber diaphragm that reacts to pressure differences. When pressure changes, the diaphragm deforms—bending or flexing—causing movement that is translated into a readable measurement, typically displayed on a dial or electronic sensor. This type of gauge is highly sensitive and accurate, especially suitable for measuring low or high vacuum pressures. It works without fluid involvement, making it reliable across various industrial applications, including vacuum systems and scientific experiments.
