Pressure sensors are mainly used in: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment and other fields.
1. It is applied to hydraulic system
The pressure sensor is mainly used to complete the closed-loop control of the force in the hydraulic system. When the control spool moves suddenly, a spike pressure of several times the operating pressure of the system can be formed in a very short time. In typical mobile and industrial hydraulics, any pressure sensor can quickly be destroyed if it is not designed with such extreme conditions in mind. It is necessary to use an impact-resistant pressure sensor, and there are two main ways for the pressure sensor to achieve impact resistance, one is to change the strain gauge chip, and the other is to connect the external coil, and the first method is generally used in the hydraulic system, mainly because of the ease of installation. Another reason is that the pressure sensor is subjected to constant pressure pulsation from the hydraulic pump.
2. Apply to safety control system
Pressure sensors are often used in safety control systems, mainly in the field of the air compressor's own safety management system. There are many sensor applications in the field of safety control, and it is not surprising that pressure sensors, as a very common sensor, are used in safety control systems.
In the field of safety control, the application is generally considered from the performance aspect, from the price consideration, as well as from the safety and convenience of the actual operation, and the actual proof is that the effect of selecting the pressure sensor is very good. Pressure sensors use the processing technology of mechanical equipment to mount components such as signal conditioners on a very small chip. So the small size is also one of its advantages, in addition, the price is also another big advantage of it. To a certain extent, it can improve the accuracy of system testing. In the safety control system, the pressure brought by the compressor is controlled to a certain extent by installing a pressure sensor in the piping equipment at 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 the equipment to the maximum power.
3. Applied to injection molds
Pressure sensors play an important role in injection molds. Pressure sensors can be installed in the nozzles, hot runner systems, cold runner systems, and mold cavities of injection molding machines, and they measure the plastic pressure somewhere between the injection molding machine's nozzle and the mold cavity during injection molding, molding, packing, and cooling.
4. It is used to monitor mine pressure
Sensor technology is one of the key technologies for mine pressure monitoring. On the one hand, we should correctly apply the various sensors that we already have to serve the mining industry; On the other hand, as a sensor manufacturer, it is also necessary to research and develop new pressure sensors to adapt to more applications in the mining industry. There are many kinds of pressure sensors, and based on the special environment of mine pressure monitoring, mine pressure sensors mainly include: vibrating wire pressure sensor, semiconductor piezoresistive pressure sensor, metal strain gauge pressure sensor, differential transformer pressure sensor, etc. These sensors have a wide range of applications in the mining industry, and the choice of which sensor to use depends on the specific mining environment.
5. Apply to promote sleep
The pressure sensor itself can not promote sleep, we just put the pressure sensor on the mattress underground, because the pressure sensor has high sensitivity, when the person turns over, heartbeat and breathing and other related actions, the sensor will analyze this series of information, to infer what state the sleeping person is in when sleeping, and then through the analysis of the sensor, collect the signal of the sensor to obtain sleep data such as heartbeat and breathing rhythm, and finally compose all the data processing into a piece of track. Of course, it can compress your night's sleep into a few minutes of music.
6. Used in compressors, air conditioning and cold equipment
Pressure sensors are commonly used in air presses, as well as air conditioning and refrigeration equipment, and these sensor products are small in size, easy to install, and the pressure guide port is generally designed with a special valve pin.
