Pressure sensors are mainly used in: petrochemical, energy and water treatment, engineering machinery, hydraulic and pneumatic systems, water conservancy and hydropower, presses, compressors, gas-liquid superchargers and other fields.
1, applied to the hydraulic system
The pressure sensor is mainly used in the hydraulic system to complete the closed-loop control of the force. When the control spool suddenly moves, a spike of several times the system operating pressure is formed in a very short time. In typical mobile machinery and industrial hydraulics, any pressure sensor can be destroyed quickly if it is not designed with such extreme conditions in mind. There is a need to use an impact-resistant pressure sensor. There are two main methods for achieving pressure resistance. One is a strain-change chip, and the other is an external coil. The first method is generally used in a hydraulic system, mainly because Easy to install. Another reason is that the pressure sensor is also subjected to uninterrupted pressure pulsations from the hydraulic pump.
2, applied to the safety control system
Pressure sensors are often used in safety control systems, mainly in the field of air compressors' own safety management systems. There are many sensor applications in the field of safety control. As a very common sensor, pressure sensors are not surprisingly used in safety control systems.
In the field of safety control, the application is generally considered from the perspective of performance. From the consideration of price, and from the convenience of practical operation, it is proved that the effect of selecting a pressure sensor is very good. Pressure sensors use mechanical processing techniques to mount components and signal conditioners on a small chip. Therefore, small size is also one of its advantages, in addition, the price is also another big advantage. To a certain extent it can improve the accuracy of system testing. In the safety control system, the pressure exerted by the compressor is controlled to some extent by installing a pressure sensor in the piping of the air outlet, which is a certain protection measure and a very effective control system. When the compressor is started normally, if the pressure value does not reach the upper limit, the controller will open the air inlet and adjust to make the equipment reach the maximum power.
3, applied to injection mold
Pressure sensors play an important role in injection molds. The pressure sensor can be installed in the nozzle of the injection molding machine, the hot runner system, the cold runner system and the cavity of the mold. It can measure the plastic from the nozzle of the injection molding machine during injection molding, filling, holding and cooling. Plastic pressure somewhere between the cavities.
4, used to monitor mine pressure
There are many types of pressure sensors. Based on the special environment of mine pressure monitoring, mine pressure sensors mainly include: semiconductor piezoresistive pressure sensors, metal strain gauge pressure sensors, and differential transformer pressure sensors. These sensors are used in a wide range of applications in the mining industry, depending on the specific mining environment.
5, applied to compressors, air conditioning equipment
Pressure sensors are commonly used in air presses, as well as air conditioning and refrigeration equipment. These sensors are small in size and easy to install, and the pressure guiding port is usually designed with a special valve pin.
