In recent years, with the development of the world, the development of high technologies such as computer technology, microelectronics, quartz tube dual-color water level table special processing technology, thin film technology, network technology, nanotechnology, etc. The mainstream of science and technology and development in the future.

The overall development trend of instrumentation products is six highs, one long, and twenty. Throughout history, analyzing the status quo and looking ahead, we can come up with the following conclusion: In the future, traditional instruments and meters will continue to move toward high performance, high precision, high sensitivity, high stability, high reliability, high environmental protection, and long life span. The direction of development. New types of instrumentation and components will be integrated into miniaturized (miniaturized), bimetal thermometers, complete sets, electronic, digital, multi-functional, intelligent, networked, computerized, integrated automation, optical and electrical In the service, specialization, simplicity, family, personalization, non-maintenance and assembly production automation, dust-free (or ultra-clean), professional, large-scale development of the 20th. The dominant, core, or key role in these 20 transformations is miniaturization, intelligence, and networking.

This background and situation have continuously raised higher, newer and more requirements for instrumentation, such as faster speed, higher sensitivity, better stability, fewer sample volumes, and minimal loss or loss of detection. Telemetering is more distant, more convenient to use, cheaper, and less polluting. It also provides a powerful impetus for the development of instrumentation technology and industry, and has become the material, knowledge, and technology foundation for the further development of instrumentation. In particular, we need to point out that in the past 10 years, due to the research results of nano-scale precision machinery, achievements in modern chemistry at the molecular level, biological research at the gene level, research achievements and global integration of high-precision and ultra-performance special functional materials. With the advent of a large number of contemporary technological achievements, including the introduction of temperature transmitter network technology promotion and application results, fundamental changes have taken place in the field of instrumentation. Through analysis, we can see 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 instrumentation and its industry development in the new century.

With the advent of fieldbus, the process of process measurement and control instrumentation has undergone a major turning point and rare opportunities. The current field bus has become a hot spot in global automation technology. Fieldbus is an open, fully digital, two-way, multi-station communication system used between on-site intelligent meters and control rooms. Its production is not only the actual demand of the vast number of users and the result of technological competition among manufacturers, but also the product and product upgrade of computer technology, communication technology and control technology in the field of industrial control, as well as the realization of further high precision and high performance. (In particular, multi-parameter on-line real-time measurement and control and automatic measurement and control), high stability, high reliability, high adaptability, multi-function, low consumption, etc. provide tremendous power and development space.
