60 years of development of instrumentation industry

The status quo of technology Most high-end markets are dominated by multinational corporations and they have a wide range of product categories. According to the national new national economic classification standard, there are 20 categories of instrumentation products, which can be classified into four categories: industrial automation instrumentation and control systems, scientific test instruments, commonly used instrumentation and special instrumentation. Among them, the most important impact on the pillar industries and major equipment of the national economy and on behalf of the industry level are two parts: the automation control system, the backbone field instruments, and the key precision testing instruments.

Automatic control systems and backbone field instruments can be roughly divided into the following four categories according to their technical level, source and market conditions.

The first type, commonly used temperature measurement, pressure measurement, flow, display and control adjustment instrument products. This kind of product is dominated by middle and low grades, product improvement and market adaptability R&D, and our company has the ability to bear.

The second category was the introduction of technology and localized products in the 1980s and early 1990s. This kind of product has already mastered the core manufacturing technology of our country's enterprise, can stabilize the production, the product has a certain market share. However, as a new generation of foreign products has matured and entered the market in large quantities, currently the products produced by Chinese companies are mainly used for small and medium-sized construction projects.

The third category is high-end products that China has developed on its own, representative products such as distributed control systems (DCS) and electromagnetic flowmeters. The basic performance and functions of these products have been close to foreign products, have a high market share, and are constantly rising. However, the application objects are still mainly small and medium-sized engineering projects. The major projects used for large-scale engineering projects are non-primary devices, non-primary control systems, and non-key work stations.

The fourth category is the high and mid-range products used in large-scale engineering projects focusing on national key projects. At present, most of the projects in China use products produced and imported by foreign-funded enterprises, such as large DCS systems, PLCs, nuclear power digital control systems and instruments, high-precision pressure/differential pressure transmitters, large pressure differentials, and wear/impact resistance. Regulators, mass flow meters, ultrasonic flow meters, and other products, as well as the use of less, technical difficulties, and strong special varieties.

Precision testing equipment The precision testing equipment developed and produced in China at this stage has reached the international level in the mid-1990s, mainly including chromatographic instruments, spectroscopic instruments, electrochemical instruments, research optical microscopes, scanning electron microscopes, electronic balances, and centrifuges. Machines, electronic universal testing machines, ultrasonic flaw detectors, X-ray flaw detectors, electronic theodolites, precision electrical measuring instruments, etc. The technological level of some products is close to and reaches the advanced level of the current international similar products, such as microwave plasma spectrometer, portable photoionization gas chromatograph, fully automatic atomic absorption spectrophotometer, atomic fluorescence spectrophotometer, laser interferometry instrument, and station Instrument, automatic intelligent ultrasonic flaw detector, automatic remote diagnostic optical microscope and so on.

At present, the products produced by Chinese enterprises can meet the general needs of scientific research, production and social aspects, but the high-end needs mainly rely on imports.
