Development level and future trend of the instrument and meter industry such as electric actuator

At present, the domestic market of high-grade scientific instrument meet rate is 30%, the low scientific instruments meet the rate of 65%; production process measurement control instrument and system products in large-scale project variety to meet the rate of 50%, the small and medium projects amounted to 70%. Imported products are often scientific research, production required major, key equipment, technical content, high added value.
Industry from scratch, from small to large, the initial formation of a relatively complete range of instruments and meters of production, research, marketing system. Built a number of scientific research and development institutions (including mechanical system of instruments, professional research 20, National Engineering Research Center for three, enterprise technology center 5, the national product quality inspection center 9); training a group of professional business, management and technical personnel. Especially some low-grade products formed their own advantages and characteristics of all kinds of digital multimeter, watt hour meter, water meter, gas meter, level meter, low optical microscope, telescope, yield the forefront of the world, to meet the basic needs of domestic needs at the same time, a large number of exports.
Through scientific and technological research, joint development, joint venture and the introduction of digestion technology absorption and localization of a variety of forms, China Instrument Industry in high-end LED products to narrow the gap with the international advanced level, and the formation of the production capacity. Independent development of major products including in Small DCS, fieldbus intelligent instrumentation, bus test system, special automobile testing equipment, ultrasonic diagnostic instrument, microwave plasma spectra, the novel diffused silicon sensitive element and recording instrument, precision small valve, new transmitter, spectrometry, chromatography, scanning electron microscope (SEM), water quality analyzer, special composite materials made of the introduction of technology of main products, the main products of the joint venture and cooperation with large DCS, EJA, flowmeter, electronic theodolite, balance testing machine, high and low temperature test instruments.
A number of state-owned, collective, private, foreign-funded enterprises and scientific research institutions by competition in the market, in the industry come to the fore, and showed a good momentum of development and potential, has become a leading, core strength.
The current level and development trend of foreign science and technology
Digital and intelligent
Due to the development of microelectronic technology, the instrument and meter product is further integrated with the microprocessor and PC technology, the digital and intelligent level of the instrument and meter is continuously improved. Taking the concept of "DSPS" proposed by the United States TI as an example, using DSP chip as the core, with the advanced mixed signal circuit, ASIC circuit, components and development tools to provide solutions for the entire application system.
Instrument with a lot of very large scale integration (VLSI) of new devices, surface mount technology (SMT), multi-layer circuit board printing, wafer scale integrated (WSI) and multi chip module (MCM) and new technology, CAD, cam, CAPP, cat computer aided means, new technology of multi media technology, human-computer interaction, fuzzy control, artificial neural networks has been widely used in modern instrumentation.
Network
At present, the development of field bus and intelligent instrument in the world presents a situation of coexistence of various bus and instruments. HART, FF, Profibus, Lonworks, WorldFIP, CAN and other bus from the application to a certain area to expand to other areas.
A variety of intelligent instruments and meters have been gradually to the market, the instrument is experiencing a profound change of intelligence. The integrated test system is also on the network, and the instruments are connected by GPIB bus and VXI bus.
miniaturization
Learned that MEMS is one of the key areas of development in the late 80's developed countries, is regarded as a new technology widely used in twenty-first Century. The sensor and signal processing technology, which is listed as one of the 22 major technologies in the United States, "have a significant impact on national security and prosperity", mainly rely on the micro technology. Application of MEMS Micro instrumentation is known for on-chip instrumentation and MEMS products including automotive accelerometer, pressure, flow rate, chemical sensors, micro spectroscopy instrument products, widely used in the field of environmental science, aerospace, Bio Medical, automotive, military, industrial control and other.
MEMS products in foreign developed countries have been industrialized, the annual growth rate of up to 10%-20%, is expected in 2001 MEMS products will form a potential market of more than $8 billion.
