Pressure sensor commonly used in safety control system

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. Among them:

1. The pressure sensor of wave pressure system is mainly used to complete the closed-loop control of force in hydraulic system. When the control valve spool moves suddenly, the peak pressure will form several times in a short time. In the following mobile machinery and industrial hydraulic pressure, any pressure sensor will be damaged soon without considering the extreme working conditions, so it is necessary to use the pressure sensor with impact resistance. There are two main ways to achieve impact resistance, one is to replace the strain chip, and the other is the external coil. The first method is generally used in hydraulic system, mainly because it is convenient to install. Another reason is that the pressure sensor must bear the uninterrupted pressure pulsation of the hydraulic pump.

2. Pressure sensor commonly used in safety control system, mainly used in safety management system of air compressor itself. As a very common sensor, it is not surprising that pressure sensor is applied in safety control system. In the field of safety control, the application is generally considered from the aspects of performance, price and the safety and convenience of actual operation. It has been 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 small size is one of its advantages, which is another advantage. It can improve the accuracy of the system test to a certain extent. In the safety control system, it is an inevitable protective measure to control the pressure brought by the compressor by installing a pressure sensor in the outlet pipeline equipment. It is also a very effective control system. When the expander is started normally, if the pressure value does not reach the upper limit, the controller will open the air inlet and make the equipment reach the maximum power through adjustment. 

3. The application of pressure sensor in injection mold 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 injection molding machine to measure the plastic force between the nozzle and mold cavity. 

4. Mine pressure sensor technology is one of the key technologies of mine pressure monitoring. On the one hand, we should correctly use all kinds of existing sensors to serve the mining industry; On the other hand, as a sensor manufacturer, we should develop and develop new pressure sensors to adapt to heavy mining applications. There are many kinds of pressure sensors, and the mine music force sensors mainly include vibrating string force sensors, semi-conductive Daleyang pressure sensors, metal strain gauge music force sensors, differential variable musical instrument music force sensors, etc. These sensors are widely used in the mining industry, and which sensor to choose according to the specific mining environment.

5. The pressure sensor used to promote sleep can't promote sleep by itself. We just put the pressure sensor under the mattress because of its high sensitivity. When people turn over, heartbeat and breathe, the sensor will analyze a series of information and infer the sleep state. Then, through sensor analysis, the sensor signals will be collected to obtain the teaching data of heartbeat and rhythm sleep, and finally all the data will be processed into tracks. Of course, your sleep can be compressed into a few minutes of music. 6. Pressure sensors used in compressors and air-conditioning cooling equipment are often used in air presses and air-conditioning cooling equipment. The sensor product is small in shape and easy to install, and the pressure guide port is generally designed with a special valve needle.
