High-tech instrumentation products, will become the future radar level gauge technology and industrial development of the mainstream of the world the past two decades, microelectronic technology, computer technology, precision machinery, high sealing technology, special processing techniques, integrated technology, thin film technology, network technology, nanotechnology, laser technology, superconducting technology, biotechnology, high technology has gained rapid development. Against this background and the situation constantly to the instrumentation higher, newer, more requirements, such as requiring faster, higher sensitivity, better stability, samples less or even non-destructive detection of micro-damage, remote sensing more long-distance remote sensing and control, more convenient, cheaper, no pollution, but also provides a powerful impetus for the development of instrumentation technology and industry, and has become the substance of the further development of instrumentation, knowledge and technical basis.

In particular should be noted that: the past decade, including nanoscale precision machinery research, the outcome of the modern study of the molecular level, gene-level biological research, research of new sensor technology and intelligent technology, and high-precision ultra- competing to come out of a large number of contemporary materials research and global networking technologies to promote application of the results of the performance of special functions, including the latest scientific and technological achievements, making the field of instrumentation to the fundamental changes these new results, not only became a modern instrumentation and industrial upon which the survival and development of soil, foundation, support, and power, but also is rapidly changing the working principle and the essential characteristics of the instrumentation, and make it available and has the traditional instrumentation simply can not match and implementation of many new, high functionality. It can be said that modern instrumentation products have become the most typical high-tech products. Currently, it has not only completely broken through the traditional light, mechanical, electrical framework, the rapid development of computerized networks, intelligent, multi-functional direction, and because a large number of high-tech science and technology research, interdisciplinary integrated design, sophisticated manufacturing technology and strict and scientific applications, thus making it is moving higher speed, more sensitive, more reliable, more simple access to analysis, detection, control object in the direction of the full range of information making big strides . Through the above analysis we can see that the high-tech is not only the main features of modern instrumentation, and is the only way to revitalize the instrument industry, the new century, instrumentation and radar level gauge, the development of the industry mainstream.

Accompanied by the advent of fieldbus, process measurement and control instrumentation development process of a major transition and rare opportunity.

Currently, on-site bus has become a hot topic of global automation technology. Fieldbus is used for a development in the field of intelligent instrumentation and control room, all digital, bi-directional, multi-station communication system. Its production, both the results of the majority of the user's actual needs and technological competition between manufacturers, but also a combination of computer technology, communications and control technologies in the field of industrial control products. Fieldbus appears, the upgrading of instrumentation, product upgrades, as well as to achieve further high-precision, high-performance (especially multi-parameter online, real-time monitoring and control and automatic monitoring and control), high stability, high reliability, high adaptability, multi-function, low consumption and other great power and space for development.

Applications, particularly non-traditional applications to further expand the continued development of the instrumentation industry has injected new vitality, new impetus to review the development process of the instrumentation industry, you can clearly see: Today, the range of applications of the instrumentation covering all areas of human activity, and is from the traditional chemical composition analysis, physical testing, mechanical measurement, astronomy, geography, observation, and industrial automatic control of the production process and product quality monitoring and control and other traditional applications, and further to the biomedical, bioengineering, expansion of non-traditional applications of the ecological environment. Meanwhile, with the high-tech and industrial development of the new century, polymer chemistry, molecular biology, life sciences, clinical medicine, pharmacy, materials, environmental monitoring and control, instrumentation, applications will also receive a more rapid expansion.

For example, the International Chemistry and Applied Spectroscopy Conference held in Pittsburgh last year proposed the concept of "morphological analysis" about the body, and hope to research and development can be "direct" observation of the various components of the body parts and chemical composition of images the instrumentation system. It can be said that modern advances in technology, more broad, more and more in-depth instrumentation applications. All this, no doubt for the further development of the radar level gauge is another powerful driving force, and shows a bright prospect.
