　　Pressure SensorMain applications: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning refrigeration equipment, and other fields.

1. Used in hydraulic systems

Pressure sensors are mainly used to complete the closed-loop control of force in hydraulic systems. When the control valve core suddenly moves, a peak pressure several times the system working pressure will form in a very short time. In typical mobile machinery and industrial hydraulic systems, if such extreme working conditions are not considered in the design, any pressure sensor will soon be damaged. Impact-resistant pressure sensors must be used. There are two main methods to achieve impact resistance. One is to replace the strain gauge, and the other is to connect an external coil. Generally, the first method is used in hydraulic systems, mainly because it is easy to install. Another reason is that it must withstand continuous pressure pulsations from the hydraulic pump.

2. Suitable for safety control systems

Pressure sensors are commonly used in safety control systems, with the main target area being the safety management system of the air compressor itself. There are many sensor applications in the safety control field. As a very common sensor, it is not surprising that pressure sensors are used in safety control systems.

In the safety control field, applications are usually considered from the perspectives of performance, price, and the safety and convenience of actual operation. It has been proven that the choice of pressure sensors is very effective. Using mechanical equipment processing technology, some components and signal regulators are installed on small chips. Therefore, small size is also one of its advantages, in addition to its low price being another major advantage. It can improve the accuracy of system testing to a certain extent. In safety control systems, by installing pressure sensors in the exhaust pipe equipment, the pressure brought by the compressor can be controlled to a certain extent. This is considered a protective measure and a very effective control system. When the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the intake and adjust it to allow the equipment to reach maximum power.

3. Used in injection molding molds

Pressure sensors play an important role in injection molding molds. Pressure sensors can be installed in the nozzle of the injection molding machine, hot runner system, cold runner system, and the cavity of the mold. They can measure the plastic pressure from the injection molding machine nozzle to the cavity during the injection, filling, holding pressure, and cooling processes.

4. Used for monitoring mine pressure

　　Pressure SensorAs one of the key technologies for mine pressure monitoring. On one hand, we should correctly apply various existing sensors to serve the mining industry; on the other hand, as a sensor manufacturer, we should also develop new types of pressure sensors to adapt to more mining industry applications. There are various types of pressure sensors, and based on the special environment of mine pressure monitoring, mining pressure sensors mainly include: vibrating wire type, semiconductor piezoresistive type, metal strain gauge type, differential transformer type, etc. These sensors have wide applications in the mining industry, and the specific type of sensor used should be selected based on the specific mining environment.

5. Used for compressors and air conditioning refrigeration equipment

Pressure sensors are commonly used in air compressors, air conditioning, and refrigeration equipment. This type of sensor product is small in size and easy to install. The pressure guiding port usually adopts a special valve needle design.
