& have spent Sensor technology is one of the important technologies of modern measurement and automation system. In People's Daily life, and the universe development road, to the ocean floor almost every technology is inseparable from the sensor. The United States as early as the 1980 s claimed that the world has gone into the era of sensor, Japan is the sensor technology as the six core technology (computer, communication, laser, semiconductor, ultrasound and sensor). The Japanese business community claims & other; Dominated the sensor technology will be able to dominate the new age & throughout; . The world technology to the development of sensor technology in the developed countries attach great importance to.

The U.S. air force in 2000, according to the authoritative data point 15 key technology helps to improve the ability of the air force in the 21st century, the second highest sensor technology. Japan in the 90 s of the development of the science and technology department of key research projects have 70 key project, including 18 is closely related to sensor technology. In our country in the late 1980 s to sensors in the focus of the national high-tech technology development, through & other Weaving & throughout; , & other Zhou & RDQ Watson instrument uo. And & other 15 & throughout; Research and industrialization of the construction, the existing more than 2000 enterprises and institutions engaged in the development, production and application of sensors. Due to the limitation of economic development level and production research and development, China's sensor industry overall technical level is relatively backward, scale and application fields are small. Today's active in the international market is still Germany, Japan, the United States, Russia and other old industrial enterprises of the country. In these countries, sensor application field is very wide, basically realize the large-scale production.

Sensors in the pressure sensor has small volume, high sensitivity, good stability, low cost and with the advantages of integrated optimization, thus develops very fast, is also widely used. Such as the use in water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemical, oil, electric power, ships, machine tools, pipe, and many other industries.

Pressure sensor is used in great quantities in the petrochemical industry in our country. But the source of most of the imports, which not only caused not only products are expensive, and not with independent intellectual property rights, is likely to be hidden potential threat. Energy can strong reactions national geological structure, energy security and the national property security. So the pressure sensor localization is imminent.
Strong and durable, widely used, it is the demand of the pressure sensor. Modern production technology to ensure the high precision and reliability, and expanding pressure test of the pressure sensor. With the development of technology, the volume of the sensor to miniaturization, intelligent and more economic and reasonable. On domestic pressure sensor also born grim reality environment. The world market demand for pressure transmitter will be increased from $2008 in 2.38 billion to $2013 in 2.798 billion, let us look forward to pressure sensor to speed up the pace of localization.
