In the sensor industry in China from traditional to new sensor is the key stage of development, it embodies the new sensors to miniaturization, multi-functional, digital, intelligent, systematic and general trend of network development. Sensor technology after years of development, the development of its technology in general can be divided into three generation:

First generation is structured sensor that USES to feelings and conversion signal structure parameter change.

The second generation is developed in the 70 s on the solid type sensor, the sensor by solid element, such as semiconductor, dielectric, magnetic materials, material is the use of certain features. Such as: using the thermoelectric effect, hall effect, photosensitive effect, respectively made thermocouple sensors, hall sensors, optical sensors.

The third generation of intelligent sensors, sensor is developed after just is the combination of the microcomputer technology and detection technology, the sensor has a certain artificial intelligence.

Sensor technology, and industry characteristics

Sensor technology and its industry characteristics can be summarized as: basic and applied at both ends may rely; Technology, investment, two intensive; Two top products and industry.

Basis, application attached to both ends

Based on attachment, it is to point to the development of sensor technology are attached to the sensitive mechanism, sensitive materials, process equipment and measuring the four cornerstones of technology. Sensitive mechanism of differ in thousands ways, sensitive material are diverse, different process equipment, measuring technique, the four cornerstone of supports, sensor technology.

Attachment is basically refers to the sensor technology application technology, its market development relies on the detection device and the application of automatic control system, can truly reflect its high additional benefits and into the real market. Means development of sensor technology to take the market as the guidance, the demand for traction.

Two intensive technology and investment

Intense technology refers to the diversity of the sensor in the process of development and manufacturing technology, borderline, integrative and skill. It is a collection of a variety of high-tech products. Due to the intensive technology intensive nature demands also talents. The sensor

The sensor

Intensive investment refers to the research, development and production of a certain sensor product requirements of a certain intensity of investment, especially in the engineering research and build economies of scale production line, more require larger investments.

Two top products and industry

Product structure and industrial structure of two big dispersion is refers to the sensor is a great variety of product categories, a total of 10 major categories, 42 small class nearly 6000 varieties), its application to infiltrate sector, its development has both the driving force of industrial development, and strongly depends on the support of the industry. Only in accordance with market demand, and constantly adjust the industrial structure and product structure, to achieve comprehensive, coordinated and sustainable development of the sensor industry.
