The sensor technology is an important part of the testing and automatic control. In the test system, as an instrument positioning, its main feature is capable of accurate transmission and the detected particular form of information, and convert it into another form of the information. Specifically, the sensor is the information determined by a measured object having feel (or response), and detection functions, and converted into corresponding thereto can be the output signal of components or devices according to certain rules. If there are no sensors measured the original information is accurate and reliable capture and conversion, all accurate test and control will not be achieved, even the most modern electronic computer, there is no accurate information (or conversion of reliable data), undistorted input will not be able to fully play its due role. Sensor technology shows below direction: 1, MEMS technology and a new generation of solid-state sensor micro-structure of the manufacturing process: deep reactive ion etching (DRIE) process or the IGP process; packaging process: such as room temperature bonding flip chip bonding stress meager structure package, multi-chip assembly process; 2, the integration process and the multi-variable composite sensor micro-structure of the integrated manufacturing process; industrial control using multivariate composite sensor; 3, intelligent technology and intelligent sensor signal wired or wireless detection, transformation processing logical judgment, functions, intelligent technology, two-way communication, self-diagnosis; smart multivariable sensors, Intelligent Sensor, and a variety of smart sensors, transmitters .4, network technology and network sensor, the sensor with industrial standard interfaces and protocols.Meanwhile, in 2020, the field of sensors and instrumentation components should seek to achieve three strategic objectives: Industrial control, automotive, communications, environmental protection as a key service areas, focusing on object sensor, elastic components, optical components, dedicated circuit, development with independent intellectual property rights of the original technology and products; To increase product variety, improve quality and economic efficiency as the main objective, to accelerate the industrialization of the varieties of domestic sensors and instrumentation components share reached 70% to 80%, more than 60% of high-end products.
