Capsule pressure gauge, the working principle of the bellows pressure gauge mainly depends on the elastic deformation characteristics of the bellows, and it is a widely used pressure measuring instrument in the industrial and scientific research fields. The following is a detailed explanation of its working principle and main application areas.

The Working Principle of Capsule Pressure Gauge      

The capsule pressure gauge measures pressure using a capsule as a sensitive element. The membrane box is made up of two or more metal thin films welded together to form a sealed chamber. When the pressure of the measured medium (such as gas or liquid) acts on the membrane box, the membrane box will produce corresponding elastic deformation according to the magnitude of the pressure. This deformation is amplified by the transmission mechanism inside the table (such as connecting rods, gears, etc.) and converted into the rotation of the pointer on the dial. The dial is engraved with pressure values, and users can obtain pressure information of the measured medium by reading the scale value pointed by the pointer.

This measurement method based on the principle of elastic deformation enables the capsule pressure gauge to accurately reflect the small pressure changes of the measured medium, and has the advantages of wide measurement range and high accuracy.

The Main Application Areas of Capsule Pressure Gauge

The capsule pressure gauge  has been widely used in multiple fields due to its unique working principle and excellent performance characteristics

Industrial field: In the industrial production process, many equipment and pipelines require precise measurement and control of pressure. Capsule pressure gauge can meet these needs and is widely used in pressure measurement and control systems in industries such as petroleum, chemical, metallurgy, and power.

In the field of scientific research, precise measurement of pressure is an important means of obtaining experimental data and verifying theoretical models. The high precision and stability of the capsule pressure gauge make it an indispensable pressure measuring instrument in scientific research experiments.

Medical equipment: In medical devices such as ventilators, blood pressure monitors, etc., precise measurement and control of gas or liquid pressure are required. The capsule pressure gauge can meet the pressure measurement needs of these devices, ensuring the accuracy and safety of medical equipment.

Other fields: In addition, capsule pressure gauge is widely used in aerospace, environmental protection, food processing and other fields, providing reliable technical support for pressure measurement and control in these areas.

In summary, capsule pressure gauge plays an important role in industry and scientific research due to its unique working principle and wide range of applications. With the continuous development of technology, the performance of capsule pressure gauge will continue to improve, and its application areas will also be further expanded.
