Some experts pointed out that the high-tech instrumentation products will become the mainstream of technology and industry development in the future. In the past two decades, microelectronics technology, computer technology, precision machinery technology High-tech, high-sealing technology, special processing technology, integrated technology, thin film technology, network technology, nanotechnology, laser technology, superconducting technology, biotechnology, etc. have achieved rapid development. This background and situation, constantly proposed to instrumentation Higher, newer, and more requirements, such as faster speed, higher sensitivity, better stability, less sample size, minimal or no loss of detection, remote sensing remote distance, easier use, and lower cost It has no strong pollution, and it also provides a powerful impetus for the development of instrumentation technology industry, and has become the material, knowledge and technical basis for the further development of instrumentation.
In particular, in the past decade, research results of precision machinery including nanotechnology, modern chemical research results at the molecular level, biological research results at the genetic level, research results of new sensor technologies and intelligent technologies, and high precision A large number of modern and recent scientific and technological achievements, including the research results of ultra-performance special functional materials and the promotion and application of global network technology, have brought about a fundamental change in the field of instrumentation [/ url]. The results have not only become the soil, foundation, support and power for the survival and development of modern instrumentation and its industry, but also rapidly changing the working principle and essential characteristics of instrumentation, and making it possess and possess the traditional instrumentation fundamentals. The numerous, new and super-high functions that can not be achieved and realized. It can be said that modern instrumentation products have become the most typical high-tech products.
At present, it has not only completely broken through the traditional framework of light, machine and electricity, but has developed rapidly in the direction of computerization, networking, intelligence and multi-functionality, and due to the extensive use of high-tech science and technology research results, interdisciplinary Comprehensive design, sophisticated manufacturing technology and rigorous scientific application make it a step forward in the direction of higher speed, more sensitive, more reliable and simpler access to all-round information analyzed, detected and controlled. . It can be seen from the above analysis that high-tech is not only the main feature of modern instrumentation, but also the only way to revitalize the instrumentation industry, and also the mainstream of instrumentation and its industry development in the new century.
With the advent of fieldbus, the development of process measurement and control instrument has experienced a major turning point and a rare opportunity. At present, fieldbus has become a hot spot in global automation technology. The fieldbus is a fully digital, two-way, multi-station communication system between the field intelligent instrumentation and the control room. Its production is not only the result of the actual needs of the majority of users and the technical competition between manufacturers, but also the combination of computer technology, communication technology and control technology in the field of industrial control. The emergence of fieldbus, for the upgrading of instrumentation, product upgrades and achieve further high precision, high performance? Especially multi-parameter online real-time measurement and control and automatic measurement and control?, high stability, high reliability, high adaptability, multi-function, low Consumption and so on provide tremendous motivation and room for development.
