China's sensor product varieties

There are a wide variety of sensor products in China. The main products are: temperature sensors, pressure sensors, weight sensors, flow sensors, liquid level sensors, oxygen sensors, force sensors, gas sensors, analytical instruments, etc., used in industrial production. There are also safety sensors, rotary encoders, vision sensors, speed sensors, and acceleration sensors such as switch proximity/positioning sensors, safety gate switches, and so on. Therefore, there is a wide variety of fields for developing sensors. The market for sensors in China has continued to grow in recent years. The general growth rate exceeds 25%. Due to the reform and opening up, China’s huge market has attracted companies from various countries, such as Siemens, Yokogawa, Honeywell, Omron, and Bonner. This brings great convenience to the end-users and industrial equipment manufacturers, while the domestic production of sensors and detection instruments has been developed, but it is far from keeping up with the needs of the situation. The scale of sensor production and R&D in various countries is continuously expanding. The United States has about 1,300 manufacturers that produce and develop sensors, more than 100 institutes and institutions, and Japan has 800 manufacturers. In recent years, China has established a national key laboratory for sensor technology, a micro/nano national key laboratory and other research and development bases, and initially established a sensor and sensor industry. The total output in 2000 exceeded 1.3 billion. At present, there are 1,688 sensors manufacturing in China. And research and development companies, of which more than 50 have been developed and produced by MEMS. By the end of the “Tenth Five-year Plan” period, the total output of sensitive components and sensors has reached 2 billion. China has also embarked on a new path in participating in the international sensor market competition, such as the Sensor National Engineering Research Center of the Shenyang Institute of Instrumentation Science and Technology. It has exported 400,000 sensor chips to the United States. The pressure sensor technology includes about 30 kinds of technology in four aspects: sensitive mechanism, sensitive material, process equipment and measurement technology. With the development of microelectronics technology, sensor technology has developed rapidly. The research and development force in China still needs a lot of investment, especially the innovation and development of sensors with independent intellectual property rights. The transformation of scientific research results and the industrialization of sensor production are even more urgent problems in China. Under mass production conditions, the performance of sensor products (mainly stability and reliability) is controlled so that the qualified rate can meet the requirements of commercialized industries. Need advanced manufacturing technology and high level of automation equipment, so we should work hard on the development of special process equipment to solve the bottleneck problem of sensor production industrialization. In the application of sensors, especially the application of new sensors, we must also vigorously promote the reform and opening up to create a market economy conditions, a variety of industrial equipment, the use of advanced sensors, which expands the sensor market, but also to China's new sensor production industry There has been momentum. In the process of sensor production industrialization, both international technology and independent innovation should be relaxed. In the introduction of foreign advanced technology, it can improve its own technology, but also meet the needs of the domestic market, forming a sensor production industry scale. For example, the diffusion silicon pressure transmitter recently released by Beijing Huijinxiang Technology Co., Ltd. is an example that can consider the introduction of technology. It has high accuracy (0.1%) and strong stability. The mass production of this type of transmitter is coordinated with automation. The reform of system management and control integration, only with strong source of information and rich information, can make informationization better promote the development of productivity. In addition, the vast market of heavy chemical industry makes new sensor transmitters used in petrochemical, metallurgy, electric power and other industries can meet the requirements of mass production.

Beijing Zhongyi Huashi is a new-type enterprise that researches, develops, manufactures, trades, and services. It holds the leading domestic thermal resistance sensing technology and industrial automatic control technology. It is a well-known domestic manufacturer of sensors and automatic control and intelligent instrumentation.
