Capsule vacuum pressure gauge is a specialized instrument used to measure vacuum pressure.
Its working principle is usually based on the deformation of capsule components to sense pressure changes. When the pressure in the vacuum system changes, the capsule will contract or expand accordingly. This mechanical motion is converted into the rotation of the pointer or the display of numbers through the transmission mechanism, providing users with accurate vacuum pressure values.
Capsule vacuum pressure gauges have high measurement accuracy and stability, and are widely used in many fields. For example, in the vacuum drying equipment of the pharmaceutical industry, it is used to monitor the vacuum degree during the drying process; In vacuum packaging equipment used in food processing, ensure that the packaging reaches the appropriate vacuum level to extend the shelf life of the food; In the vacuum experimental device of the research laboratory, it helps researchers to accurately control and measure vacuum conditions.
This type of pressure gauge is typically used to measure lower vacuum pressures, with Mbar as the unit of pressure. The Bourdon tube is its core pressure sensing element. When the pressure changes, the Bourdon tube will produce corresponding deformation, thereby driving the pointer or other indicating device to display the pressure value.
For example, in some vacuum coating equipment, vacuum systems in semiconductor manufacturing processes, or vacuum environment monitoring in scientific research experiments, this capsule vacuum low-pressure Bourdon tube pressure gauge may be used to accurately measure and monitor changes in vacuum pressure.
