Development of China's experimental instrument industry

The overall technical level of China's experimental instrument industry has reached the international level in the mid-1980s. Microelectronics and computer technology are commonly used in experimental instrument products. About 15% of products have achieved intelligence and reached the level of the international 90s; 30% of the products have been realized. Digitalized, reaching the international level in the late 1980s. The comprehensive service capability was significantly improved: It can undertake complete control projects for 300,000-600,000 kilowatts of thermal power plants, nuclear power plants, 300,000 tons of synthetic ammonia, 120 tons of converters, 300,000 cubic meters of city gas station projects, and large-scale furnaces and kilns.

The industry started from scratch and grew from small to large, and initially formed a relatively complete range of experimental instrument production, research, and marketing systems. A number of R&D institutions have been established (including 20 professional instrumentation institutes for mechanical systems, 3 state-level engineering research centers, 5 enterprise technology centers, and 9 national product quality inspection centers); Management, management, technical personnel. In particular, some middle- and low-end products have formed their own advantages and characteristics. Various digital multimeters, power meters, water meters, gas meters, level meters, middle and low-end optical microscopes, and telescopes have produced the world's most advanced products. While basically satisfying domestic needs, they have exported a lot of goods. .

Through scientific and technological research, joint development, joint ventures, and the introduction of imported technologies to digest and absorb various forms of domestic production, China's instrumentation industry, some of the high-end leading products narrowed the gap between the international advanced level, and the formation of production capacity. The main products independently developed include small and medium-sized DCS, fieldbus smart meters, bus-type test systems, automobile-specific testing equipment, ultrasonic diagnostic instruments, microwave plasma spectroscopy, and new diffusion silicon sensitive components. The main products introduced in the localization of technology are recorded. Instruments, precision small control valves, new transmitters, spectroscopy, chromatography, scanning electron microscopes, water quality analyzers, special composite materials, etc.; major products of joint ventures and cooperation are large DCS, EJA, flow meters, electronic theodolites, dynamic balance testing machines, High and low temperature test equipment.

The major products meet the needs: the domestic market satisfaction rate for middle-to-high-end scientific test instruments is 30%, and the satisfaction rate for middle-to-low-grade scientific instruments is 65%; the product satisfaction rate for measurement and control instrumentation and system products for production processes in large-scale engineering projects reaches 50%. 70% of small and medium-sized projects. Imported products are often the major and key equipment required for scientific research and production, with large technological content and high added value.

A group of state-owned, collective, private, and foreign-funded enterprises and research institutes have emerged from the industry through market competition, and have shown good momentum of development and stamina. They have formed a dominant and core force.
