As an important automatic control device, pressure switches are widely used in various industrial automation systems to monitor and control pressure changes in liquid or gas systems. Pressure switches can be divided into various types according to their different working principles, structural features and application fields.
The following is a brief introduction to several common types of pressure switches.
1.Mechanical contract pressure switch:
This type of switch uses mechanical components such as springs, diaphragms or bellows as pressure-sensitive components. When the pressure changes, these components deform, thereby driving the contacts to close or open.
They have a simple structure and low cost, and are widely used in applications where control accuracy requirements are not extremely high.
2.Electronic pressure switch：
Unlike mechanical type, electronic pressure switches have built-in pressure sensors and signal processing circuits, which can sense pressure changes more accurately and transmit and control them through electronic signals.
They have the advantages of high stability and programmability, and are particularly suitable for occasions requiring remote monitoring and automatic control.
3.Differential pressure switch:
Differential pressure switches focus on measuring the pressure different between two points and are commonly used to monitor fluid flow status, filter blockage or liquid level changes.
In systems where precise control of fluid balance or monitoring of dynamic fluid changes is required, the differential pressure switches play an irreplaceable role.
4.Intelligent pressure switch:
With the development of internet of IoT technology, intelligent pressure switches have emerged. They not only have the functions of traditional pressure switches, but can also exchange data with upper-level machines or cloud platforms through wireless communication to achieve remote monitoring, fault diagnosis and intelligent control, etc.
Pressure switches have become an indispensable part of industrial automation and control systems with their unique functions and wide application areas.
As technology advances and application needs expand, the types and performance of pressure switches will also continue to be upgraded and improved.
