The tens of billions market is calling, and the development of pressure sensors is entering the fast lane

Sensors play a very important role in the era of Industry 4.0. Sensing technology is the entrance of data collection and the foundation and core of big data analysis. With the accelerated implementation of technologies such as 5G, the Internet of Things, artificial intelligence, and autonomous driving, the increasingly large and complex data requirements will dramatically enlarge the sensor market, and the industry prospects will be very bright. develop. With the application and promotion of the Internet of Things in the industrial field, the application of sensors in it is more and more extensive. Depending on the type of sensor, it includes temperature and humidity sensors, pressure sensors, image sensors, light sensors, position sensors, gravity sensors, etc. In the global sensor market, flow sensors, pressure sensors and temperature sensors account for a large proportion. It is understood that the pressure sensor refers to the conversion of the received pressure signals such as gas and liquid into standard current signals (4~20mADC) to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement, indication and process adjustment. components. It is mainly composed of load cell sensors, measurement circuits and process connections. As far as the current market is concerned, pressure sensors generally include differential pressure sensors, absolute pressure sensors, gauge pressure sensors, static pressure sensors and dynamic pressure sensors. For the relationship between these two, we can define it as follows: Differential pressure is the difference between two actual pressures. When one of the actual pressures in the differential pressure is atmospheric pressure, the differential pressure is the gauge pressure. Absolute pressure is actual pressure, and what makes sense is gauge pressure, gauge pressure = absolute pressure - atmospheric pressure. Static pressure is the pressure at which the fluid in the pipe is not flowing. Dynamic pressure can be simply understood as the pressure that occurs after the fluid flows in the pipeline. According to incomplete statistics, there are nearly 2,000 manufacturers engaged in the production of various pressure transmitters in my country. Pressure sensors are the most commonly used sensors in industrial practice. They are widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent Construction, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries, the development prospects are promising. Over 10 billion, the development of pressure sensors has entered the fast lane. According to data, the scale of my country's sensor market has maintained rapid growth in recent years. It is expected that by 2021, the scale of my country's sensor market may exceed 200 billion yuan. There is no doubt that China's sensor industry is growing rapidly. Ushering in the golden age of development, this will also bring huge development opportunities for domestic sensor companies. Among them, the pressure sensor market scale exceeds 10 billion, and the development is entering the fast lane. my country's pressure sensor market is mainly in the field of industrial automation and control, and the field of automobiles. In the field of industrial control, the vast majority of our country currently uses diffused silicon pressure sensors, strain gauge pressure sensors and sputtering thin film pressure sensors, and domestic manufacturers produce a large number of diffused silicon pressure sensors. The growth of the pressure sensor market is mainly driven by the development of micro-electromechanical systems (MEMS), increasing demand from the automotive and medical industries, stringent government regulations, and adoption of smart technologies. It is predicted that in 2024, the pressure sensor market will grow at a compound annual growth rate of 6.3%. It is expected that the pressure sensor market will grow from $17.4 billion in 2019 to $23.6 billion in 2024, and related companies can focus on layout. Focus on layout and understand the development trend of pressure sensors. The data shows that in order to develop pressure sensors, the development model must accelerate the formation of a one-stop industrialization from sensor research and development to large-scale production, and take a leap-forward development path combining independent innovation and international cooperation. , making my country a major producer of sensors in the world; the structure of sensor products is developing in a comprehensive, coordinated and sustainable manner. Product varieties should be inclined to high technology and high added value, especially to fill“blank”Variety. Furthermore, the production pattern is developing towards specialization; the key technological transformation of pressure sensor enterprises should be strengthened from relying on imported technology to the digestion and absorption of imported technology and the direction of independent innovation; business operations should accelerate from the domestic market to both domestic and foreign. The direction of internationalization combined with each market will leapfrog development; the enterprise structure will be“Large, medium and small”,“Group and specialized production coexist”pattern development. Finally, sensors are the basis for humans to accurately perceive, manufacture, process and operate everything in the world. Sensors play an increasingly important role in the field of science and technology, industrial and agricultural production, and daily life. It can be said that it is difficult to have high-precision measurement and sensing applications without sensing technology. According to the types of sensors, pressure sensors occupy the top three market shares in my country. The tens of billions market is calling. The development of pressure sensors is entering the fast lane. Relevant companies can understand the development trend of pressure sensors and formulate corresponding pressure sensors according to their own development. development strategy to seize development opportunities.
