To provide you with the latest and most timely green technology information and market trends
Instruments and meters are used to detect, measure, observe, calculate various physical quantities, material composition, physical parameters and other appliances or equipment. Vacuum leak detector, pressure gauge, length measuring instrument, microscope and multiplier are all instruments.
In recent years, the instrument industry presents a trend of rapid development. A statistical data from China Instrument Association shows that the output and sales of China instrument industry continue to rise after two years of high growth. In the first half of 2007, the total output value of China instrument industry reached 133.5 billion yuan, up 29.1% year on year; The product sales revenue was 128.9 billion yuan, up 30.7% year on year, both of which were at a historical high; The year-on-year growth rate of profits is more than 40%, and the year-on-year growth rate of total assets is about 18%. The industry as a whole is in a benign development stage.
Current market analysis
The domestic market share of medium and low-grade electrical instrument products has reached 95%. The domestic market share of high-grade products and the foreign market share of medium and low-grade products have been greatly increased on the existing basis. The market development of China's instrument industry in 2010 is expected to improve. The goal of product structure adjustment. Among them, industrial automation instruments focus on the development of main control system devices based on fieldbus technology, intelligent instruments, special and special automation instruments. The technical level of the products has reached the advanced level of foreign countries in the late 1990s, and the sales volume in 2005 accounted for 30% of the sales volume of domestic instruments. We should face the market, expand the service field in an all-round way, promote the digitization, intellectualization and networking of instrument system, and complete the transformation of automatic instrument from analog technology to digital technology. At the end of the tenth five year plan, the number of digital instrument varieties reached more than 60%.
Future development trend
The progress of science and technology constantly puts forward higher and newer requirements for instruments. The development trend of instruments and meters is to constantly use new working principles, new materials and new components, such as ultrasonic, microwave, ray, infrared, nuclear magnetic resonance, superconductivity, laser and other principles, as well as various new semiconductor sensitive components, integrated circuits, integrated optical path, optical fiber and other components. Its purpose is to realize the miniaturization of instruments, reduce the weight, reduce the production cost and make it easier to use and maintain. Another important trend is to improve the performance of instruments and meters through the use of microcomputers, so as to improve the automation, intelligence and data processing ability of instruments and meters. Instruments and meters are not only for single use, but also may be combined with electronic computer through standard interface and data channel to form a variety of test control management integrated system to meet higher requirements.
Industrial automation instruments focus on the development of main control system devices based on fieldbus technology, intelligent instruments, special and special automation instruments; We will expand the service field in an all-round way, promote the digitization, intellectualization and networking of instrumentation systems, and complete the transformation of automation instrumentation from analog technology to digital technology. Within five years, the proportion of digital instrumentation will reach more than 60%; Promote the commercialization of automation software with independent copyright.
