I. What are Bourdon Tube Pressure Sensors?

Bourdon tube pressure sensors are a commonly used type of pressure sensor in the electronic components industry. They are mechanical devices that measure pressure changes by utilizing the deformation of a Bourdon tube. Typically made from metal, these sensors feature a curved tube structure sealed at one end and connected to a pressure measurement system at the other.

II. Working Principle

The operating principle of Bourdon tube pressure sensors is based on the physical properties of elastic deformation. When pressure is applied to the Bourdon tube, the cross-sectional shape of the tube changes, causing the tube walls to bend or twist. This deformation alters the tension, strain, or displacement inside the Bourdon tube, thereby changing the electrical characteristics (such as resistance, capacitance, or other electrical properties) of the sensor system connected to it. By measuring these electrical changes, the sensor accurately determines the magnitude of the pressure.

III. Characteristics and Advantages

Bourdon tube pressure sensors possess several notable characteristics and advantages:

· Simple Structure: Constructed primarily from a single metal tube, they offer a relatively low manufacturing cost.

· Fast Response: Capable of promptly responding to pressure variations, suitable for dynamic measurement requirements.

· Durability: Selected for their mechanical strength and corrosion resistance due to the metal materials used.

· High Accuracy: Providing precise pressure measurements to meet stringent control requirements.

· Wide Adaptability: Applicable across various media and environmental conditions for pressure measurement.

IV. Applications

Bourdon tube pressure sensors find extensive applications in the following fields:

· Industrial Automation: Monitoring and controlling pressure changes in industrial processes, such as within liquid and gas pipeline systems.

· Automotive Engineering: Used in engine management systems, braking systems, and air conditioning systems for real-time pressure monitoring and adjustment.

· Medical Equipment: Employed in devices like respirators and blood pressure monitors to accurately measure and control pressure changes.

· Consumer Electronics: Integrated into devices such as smartphones and tablets for barometric pressure measurement functionalities.

V. Conclusion

Bourdon tube pressure sensors are indispensable components within the electronic components industry, renowned for their straightforward yet reliable operational principles and broad application scope. As technology advances and application areas expand, these sensors continue to play an increasingly pivotal role in enhancing system performance, optimizing production processes, and elevating product quality.
