Application field of pressure sensor
Pressure sensors are mainly used in: booster cylinder, supercharger, gas-liquid booster cylinder, gas-liquid supercharger, press, compressor, air conditioning and refrigeration equipment and other fields.
1, for hydraulic system
Pressure sensor is mainly used to complete the closed-loop control of force in hydraulic system. When the control valve spool suddenly moves, it will form a peak pressure several times the working pressure of the system in a short time. In typical mobile machinery and industrial hydraulic systems, any pressure sensor will be destroyed quickly if this extreme working condition is not considered in the design.
It is necessary to use an impact-resistant pressure sensor. There are two main methods to realize shock resistance of pressure sensor, one is to replace the strain chip, and the other is to connect the disk tube. Hydraulic system generally adopts the first method, which is mainly convenient to install. In addition, another reason is that the pressure sensor must bear the uninterrupted pressure pulsation from the hydraulic pump.
2. Applied to safety control system
Pressure sensors are often used in safety control systems, mainly for the safety management system of air compressors. There are many applications of sensors in the field of safety control, and it is not surprising that pressure sensors are used in safety control systems as a very common sensor.
The application in the field of safety control is generally considered from the aspects of performance, price, safety and convenience of actual operation. Practice has proved that the effect of selecting pressure sensor is very good. The pressure sensor uses the processing technology of mechanical equipment to install some components and signal regulators on a small chip.
So its small size is also one of its advantages. In addition, its low price is another big advantage. To some extent, it can improve the accuracy of system testing.
In the safety control system, it is a certain protective measure and a very effective control system to control the pressure brought by the compressor within a certain range by installing a pressure sensor in the pipeline equipment at the air outlet.
When the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the air inlet and make adjustments to make the equipment reach the maximum power.
3. Apply to injection mold
Pressure sensor plays an important role in injection mold. Pressure sensors can be installed in the nozzle, hot runner system, cold runner system and mold cavity of injection molding machine, and can measure the plastic pressure somewhere between the nozzle and mold cavity of injection molding machine during injection molding, mold filling, pressure maintaining and cooling.
4. It is used to monitor the ground pressure.
Sensor technology is one of the key technologies of mine pressure monitoring. On the one hand, we should correctly apply all kinds of existing sensors to serve the mining industry; On the other hand, as a sensor manufacturer, it is necessary to research and develop new pressure sensors to adapt to more mining applications.
There are many kinds of pressure sensors, which are 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 and so on. These sensors are widely used in mining industry, and which sensor to use depends on the specific mining environment.
5. Use it to promote sleep
Pressure sensors themselves do not promote sleep. We just put the pressure sensor under the mattress. Because of its high sensitivity, the sensor will analyze this series of information when people turn over, heartbeat and breathe.
To infer what state the sleeper is in, and then through the analysis of sensors, collect sensor signals to get sleep data such as heartbeat and breathing rhythm, and finally process all the data into a piece of music, which can of course compress your sleep at night into a piece of music for a few minutes.
6. Used in compressors, air conditioners and cooling equipment.
Pressure sensors are often used in air presses and air conditioning refrigeration equipment. These sensor products are compact in appearance and easy to install, and the pressure guide port is generally designed with a special valve needle.
