A pressure switch is a switching component widely applied in automation systems of chemical, machinery, power, environmental protection and other industries, for measuring air, gas and liquid pressure
With the increasing application of pneumatic equipment in industrial automation, intelligent manufacturing and other fields, requirements on control accuracy, efficiency and other aspects have become more stringent.

Now let’s discuss what extra advantages the digital pressure switch (air pressure detection and control device) has over conventional units.
First, its working principle: A pressure switch mainly detects pressure at the measuring point. Built-in sensors sense external pressure. When the pressure exceeds or falls below the preset threshold, the sensor diaphragm deforms and outputs control signals to trigger switch actions. When pressure returns to the normal threshold, the internal diaphragm resets automatically. Combined with dedicated CPU modular signal processing technology, it realizes detection, display, alarm and control signal output of medium pressure signals to prevent potential safety hazards.
Superior Structure & Performance
1. Flexible and Easy Installation. Most adopt British pipe thread quick connectors or copper tube welded mounting structure, requiring no extra fixtures for simple installation.
2. Convenient Modification. After installation, connection modes can be adjusted by changing terminal wiring for use with other equipment.
3. Strong Anti-interference Performance. The sensor is housed inside sealed components, less susceptible to external interference to maintain stable operation.
4. Customization Available. Manufacturers can design products with different specifications and supply in batches to meet personalized requirements of customers.
In summary, pressure switches deliver these benefits thanks to two sensing elements: a threaded tube and a diaphragm.
The threaded tube is made of stainless steel, phosphor bronze and other materials. Although relatively costly, it features a wide adjustable differential range and excellent durability for high stability.
The diaphragm is made of NBR, fluororubber and other materials with great corrosion resistance. It automatically senses external pressure and enables the switch to detect, display and output signals timely.
Based on this, digital pressure switches allow direct visual reading of pressure values and easier parameter adjustment by users.
This type of equipment has existed for quite a long time.
