Application fields of pressure sensors

Pressure sensors are mainly used in: booster cylinders, superchargers, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air-conditioning and refrigeration equipment and other fields.
1. Applied to 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 moves suddenly, a peak pressure several times the system working pressure will be formed in a very short time. In typical mobile and industrial hydraulics, any pressure sensor would quickly be destroyed if it was not designed for such extreme conditions. It is necessary to use an anti-shock pressure sensor. There are two main methods for the pressure sensor to achieve anti-shock, one is to change the strain gauge chip, and the other is to connect an external coil. Generally, the first method is used in the hydraulic system, mainly because Easy to install. Another reason is that the pressure sensor is subjected to constant pressure pulsations 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 the air compressor itself. There are many sensor applications in the field of safety control. As a very common sensor, it is not surprising that pressure sensors are used in safety control systems.
The application in the field of safety control is generally considered in terms of performance, price, and safety and convenience of actual operation. It has been proved that the effect of choosing a pressure sensor is very good. The pressure sensor uses the processing technology of mechanical equipment to install some components and signal conditioners on a small chip. So small size is also one of its advantages, in addition, cheap price is another major 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 pipeline equipment at the gas outlet. This is a certain protection measure and a very effective control system. When the compressor starts normally, if the pressure value does not reach the upper limit, then the controller will open the air inlet to make the equipment reach the maximum power through adjustment.
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 flow of plastic from the nozzle of the injection molding machine to the Plastic pressure somewhere between cavities.
4. Applied to monitor mine pressure
Sensor technology is one of the key technologies for mine pressure monitoring. On the one hand, we should correctly apply various existing sensors to serve the mining industry; on the other hand, as a sensor manufacturer, we must develop 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 sensors, semiconductor piezoresistive pressure sensors, metal strain gauge pressure sensors, differential transformer pressure sensors, etc. These sensors are widely used in the mining industry, and which sensor to use depends on the specific mining environment.
5. Applied to promote sleep
The pressure sensor itself cannot promote sleep. We just put the pressure sensor under the mattress. Due to the high sensitivity of the pressure sensor, when people turn over, heartbeat, breathing and other related actions, the sensor will analyze this series of information to infer sleep. What is the state of a person sleeping, and then through the analysis of the sensor, the signal of the sensor is collected to obtain the sleep data such as heartbeat and breathing rhythm, and finally all the data is processed and composed into a piece of music, which of course can compress your night's sleep into a song. Music for the first few minutes.
6. Applied to compressors, air-conditioning and cooling equipment
Pressure sensors are often used in air compressors and air-conditioning and refrigeration equipment. This type of sensor product is small in size and easy to install. The pressure guide port generally adopts a special valve needle design.
