Sensors and instrumentation components is one of the most basic components in instrumentation and automation systems. Sensors and instrumentation components has the demand for services is wide, wide variety, the major characteristics and its technical level and improve the quality of our products, will lay the foundation for Chinese manufacturing's informatization.
 
Current situation and problems
 
Sensors and instrumentation technology and products in our country, through the development, have greatly improved. The country has more than 1600 enterprises and institutions engaged in the development of sensors and instrumentation components, development and production. But compared with abroad, in China, the varieties of sensors and instrumentation components and quality level, and cannot meet the needs of the domestic market, the level of the overall level is still in the abroad in the early 1990 s. Main problems are:
 
(1) science and technology innovation, the core manufacturing technology seriously lags behind foreign countries, with independent intellectual property rights of products, variety is not complete, the product technology level and foreign 15 years or so.
 
(2) the investment strength is low, the scientific research equipment and production technology and equipment backward, low level of achievements, product quality is poor.
 
(3) science and technology and production, affect the conversion of scientific research, comprehensive strength is low, the lagged industrial development.
 
Strategic objectives
 
By 2020, the field of sensors and instrumentation components should strive to achieve the three strategic objectives:
 
With industrial control, automotive, communications, environmental protection for key services, to sensor, elastic components, optical components, dedicated circuit as the key object, development with independent intellectual property rights of original technology and products;
 
Based on the MEMS technology, integration, intelligence and network technology as the backing, to strengthen the development of new sensors and instrumentation components manufacturing process and, to leading products and close to the advanced level of similar foreign products;
 
To increase the variety, improve quality and economic benefit as the main target, accelerate the industrialization, the domestic varieties of sensors and instrumentation components share reached 70% ~ 70%, high grade product of more than 60%.
 
Development priorities
