instrumentation products will surely become the mainstream of the development of instrumentation technology and industry in the future. In the past 20 years, microelectronics technology, computer technology, precision machinery technology, high sealing technology, special processing technology, integrated technology, thin film technology, network technology, nanotechnology, laser technology, superconducting technology and biotechnology have developed rapidly. This background and situation constantly put forward higher, newer and more requirements to instruments, such as faster speed, higher sensitivity, better stability, less sample volume, micro-damage or even non-destructive detection, remote sensing and telemetry, more convenient use, lower cost, no pollution, etc., and also provide a strong driving force for the development of instrument technology and industry, and became the material, knowledge and technical basis for the further development of instrumentation.

In particular, it should be pointed out that in the past 10 years, due to the research results of nanoscale precision machinery, the research results of modern chemistry at the molecular level, and the rapid development of science and technology and the continuous improvement of automation, my country's instrumentation The industry will also undergo new changes and obtain new developments.

In particular, it should be pointed out that in the past 10 years, due to the research results of nanoscale precision machinery, modern chemical research results at the molecular level, biological research results at the gene level, and research results of high-precision super-performance special functional materials A large number of contemporary latest technological achievements, including the results of the promotion and application of global network technology, have undergone fundamental changes in the field of instrumentation. Through the analysis, it can be seen that high-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrument industry, and it is also the mainstream of the development of instrumentation and its industry in the new century.

With the advent of fieldbus, the development of process measurement and control instruments has undergone a major turning point and a rare opportunity.

At present, fieldbus has become a hot spot in global automation technology. Fieldbus is an open, all-digital, two-way, multi-station communication system between field intelligent instruments and control room. Its emergence is not only the result of the actual needs of the majority of users and the technical competition among manufacturers, but also the product and product upgrade of the combination of computer technology, communication technology and control technology in the field of industrial control, and to achieve further high precision, high performance (especially multi-parameter online real-time measurement and control and automatic measurement and control), high stability, high reliability and high adaptability, multi-function and low consumption provide great power and development space.

Application areas, especially the further expansion of non-traditional application areas, have injected new vitality and new impetus into the sustainable development of the instrumentation industry. The overall development trend of

instrumentation products is "six high and long" and "twenty". Throughout history, analyze the present situation and look forward to the future, the following conclusions can be drawn: in the future, traditional instruments and meters will still develop in the direction of "six high and one long" with high performance, high precision, high sensitivity, high stability, high reliability, high environmental protection and long life. New instruments and components will move towards miniaturization (miniaturization), integration, complete sets, electronics, digitization, multi-function, intelligence, networking, computerization, comprehensive automation, opto-mechatronics; Specialization, simplicity, familiarization, personalization, non-maintenance, and assembly and production automation, dust-free (or ultra-clean), specialization, and large-scale "twenty" development. In this "twenty", the dominant, core or key role is miniaturization, intelligence and networking. With the rapid development of science and technology and the continuous improvement of the degree of automation, China's instrumentation industry will also undergo new changes and obtain new development.
