China has more than 1,600 enterprises and institutions engaged in sensor and instrumentation components of the development, production. However, compared with foreign countries, China's sensor and instrumentation components of the product types and quality level, still cannot meet the needs of the China market, the overall level is still in the early 1990s, the level of the early 90s. Anyway China's sensors and instrumentation technology and products have been greatly improved a lot.
The main problems are:
(1) Poor technological innovation, the core manufacturing technology seriously lagging behind abroad, with independent intellectual property rights of small products, incomplete varieties, product technology and foreign differences of about 15 years.
(2) Technology and production out of line, affecting the transformation of scientific research, comprehensive strength is low, lack of industry development potential.
(3)Low investment intensity, scientific research equipment and production technology equipment backward, low level of results, poor product quality.
(1) MEMS technology and a new generation of solid-state sensor microstructure manufacturing process: deep reactive ion etching (DRIE) process or IGP process; packaging process: such as room temperature bonding flip-chip welding, stress-free structure package, multi-chip assembly process; New sensors: such as micro-silicon capacitive sensors, micro-silicon mass flow sensors, aerospace dynamic sensors, micro-sensors, automotive pressure, acceleration sensors, environmental protection with micro-chemical sensors.
(2) Integrated technology and multivariable composite sensor microstructure integrated manufacturing process; industrial control with multi-variable composite sensor, such as: pressure, static pressure, temperature three variable sensors, air pressure, wind, temperature, humidity four variable sensors, micro silicon composite Strain sensor, display sensor.
(3) intelligent technology and intelligent sensor signal wired or wireless detection, transformation processing, logic judgment, functional calculation, two-way communication, self-diagnosis and other intelligent technology; intelligent multi-variable sensor, intelligent power sensor and a variety of intelligent sensors, Device.
(4) Networked technology and networked sensors, so that the sensor has an industrial standard interface and protocol functions.
Flexible components to develop and improve the new molding process: electrode position molding process, welding molding process; focus on the development of aviation, aerospace with low stiffness, large displacement, long life micro-precision bellows, high temperature and high pressure valve bellows; Development of bellows efficient molding process equipment and performance testing equipment.
Sensors and instrumentation components are one of the most basic components of instrumentation and automation systems. Sensors and instrumentation components with a wide range of services, wide variety, demand and other characteristics of its technical level and product quality improvement, will lay the foundation for China's manufacturing information.
