Development of instrumentation

The instrumentation industry has shown rapid development in recent years. Today, although the instrumentation industry has developed rapidly, the gap with foreign countries is still relatively large. It is reflected in the slow progress in technological innovation and industrialization; the lack of key core technologies, the low level of repeated abnormalities, and the long-term stability and reliability of products. Less than a fundamental solution; a large number of imports have a major adverse impact on the development of the industry.

However, in the instrumentation industry, there is still a big gap between domestic products and foreign products. Domestic instrumentation is still not favored by the domestic market, and due to certain reasons, it restricts the development of the industry. However, China has its own advantages, advantages and disadvantages coexist, let us turn the disadvantages into "motivation" and develop the advantages to the end.

Analysis of domestic instrumentation First, China is a developing country, and the instrumentation industry has a gap of 10 to 15 years compared with developed countries. However, in the developing countries, China is the largest and most complete and most powerful country in the instrumentation industry.

Second, China’s demand for instruments and meters is one of the fastest growing countries. The growth rate of instrumentation in the world is 3% to 4%. China has achieved an annual growth rate of more than 20% for four consecutive years, and some products already account for one-tenth of the world's total.

Third, at present, the instrumentation industry is a sector that directly competes with foreign companies. Foreign investment has entered the third phase in China. The first stage is the joint venture and technology export. The second phase of the joint venture between the 1990s and the 20th century is now entered into the third phase, which is dominated by wholly-owned and merged Chinese outstanding companies.

Fourth, some middle and low-end products already have scale advantages and international market competitiveness. For example, ordinary digital multimeters and other products account for a large amount of production in the world, and household electrical meters have a production capacity of 50% of the world's total. At present, China has become a major producer and exporter of electricity meters, microscopes, telescopes, thermometers, pressure gauges, water meters, gas meters, and optical components. Exports of high-end products such as container inspection equipment have also begun to make breakthroughs.

In-depth industry research In technology, the existing domestic middle and low-end products can replace most of the imported products, and the reliability index of high-end products, that is, the average time between failures and foreign products is about 1-2 orders of magnitude.

In terms of measurement accuracy, existing domestic products and foreign products generally differ by one order of magnitude. Because China's basic technology and manufacturing process of the instrument are not adequately studied, some key technologies that affect reliability, such as precision machining technology, sealing technology, and welding technology, have not yet been well resolved, resulting in products, especially high-end products. The performance is not stable enough and reliable.

In terms of function, at present, the degree of intellectualization of foreign production is quite high. Through the digital processing of original information, the influence of external interference on information is better eliminated, and the environmental resistance and measurement authenticity of the product are improved. However, the current level of domestic product intelligence is still relatively low.

In addition, the networking of products has entered a practical stage in foreign countries, and our country is basically in its infancy, thus making the product's performance and function backward.
