Application Areas Of Pressure Sensors
Pressure sensors are widely used in: booster cylinder, supercharger, gas-liquid booster cylinder, gas-liquid supercharger, press, compressor, air conditioning refrigeration equipment and other fields.
1, applied to hydraulic system
The pressure sensor in the hydraulic system is mainly to complete the closed loop control of the force. When the control spool moves suddenly, a spike pressure several times the working pressure of the system will be formed in a very short time. In typical walking machinery and industrial hydraulics, any pressure sensor that is not designed with such extreme conditions in mind will soon be destroyed. It is necessary to use impact-resistant pressure sensors. There are two main methods to achieve impact resistance of pressure sensors, one is to change strain chip, the other is to connect external coil. Generally, the first method is used in hydraulic system, mainly because of the convenience of installation. Another reason is that the pressure sensor is also subjected to the continuous pressure pulsation from the hydraulic pump.
2. Apply to the security control system
Pressure sensors are widely used in the safety control system, and the main field is the safety management system of air compressor itself. There are many sensor applications in the field of security control. As a very common sensor, it is not surprising that pressure sensor is used in security control system.
In the field of safety control applications generally from the performance of the consideration, from the cost of consideration, and from the actual operation of safety and convenience to consider, the actual selection of pressure sensor has been proved to be very good effect. Pressure sensors use mechanical processing techniques to mount components and signal regulators on a small chip. So small size is also one of its advantages, in addition, cheap price is another big advantage. To a certain extent, it can improve the accuracy of system testing. In the safety control system, pressure sensors are installed in the pipeline equipment of the air outlet to control the pressure brought by the compressor to a certain extent, which is a certain protection measure and a very effective control system. When the compressor starts normally, if the pressure does not reach the upper limit, then the controller will open the air inlet and adjust the equipment to reach the maximum power.
3. Applied to injection mold
Pressure sensor plays an important role in injection mold. The pressure sensor can be installed in the nozzle, hot runner system, cold runner system and mold cavity of the injection molding machine. It can measure the plastic pressure somewhere between the nozzle of the injection molding machine and the mold cavity during the injection molding, filling, holding pressure and cooling process.
4. Application in monitoring mine pressure
Sensor technology is one of the key technologies in mine pressure monitoring. On the one hand, we should correctly apply the existing sensors to serve the mining industry; On the other hand, as sensor manufacturers also need to develop and develop new pressure sensors to adapt to more mining industry applications. There are many kinds of pressure sensors. Based on the special environment of mine pressure monitoring, mine pressure sensors mainly include: vibrating string pressure sensor, semiconductor piezoresistive pressure sensor, metal strain gauge pressure sensor, differential transformer pressure sensor and so on. These sensors have a wide range of applications in the mining industry, and the specific sensors used can be selected according to the specific mining environment.
5. Use to promote sleep
Pressure sensor itself unable to promote sleep, we just put pressure sensor mattresses, due to the pressure sensor with high sensitivity, when people turn, heart rate and breathing and related actions, the sensor will analyze this a series of information, to infer that sleep sleep in what a state, and then through the analysis of the sensor, Collect sensor signals to get sleep data such as heart rate and breathing rhythm, and finally compose all the data into a piece of music, of course, can compress your night's sleep into a few minutes of music.
6. Used in compressors, air conditioners and cold equipment
Pressure sensors are widely used in air presses, as well as air conditioning and refrigeration equipment, this kind of sensor products small appearance, easy installation, pressure guide port generally adopts special valve needle design.
