China's machine tool industry has low concentration, low-end mismatch and high-end failure. The backwardness of key accessory parts and products is an important reason for the backward development of CNC machine tools. According to the survey data, the economic, mid-range and high-end ratios of CNC machine tools produced in China five years ago were about 70:29:1, while those in Japan and the United States were 0:80:20 and 0:60:40 respectively. The core CNC system, the domestic mid-range CNC system market share of about 20%, high-end CNC system occupancy rate is less than 5%, heavily dependent on imports. At present, the state has formulated special plans for high-end CNC machine tools and basic manufacturing, mainly for the high-end CNC machine tools in China's aerospace, shipbuilding, automotive and power generation equipment industries, and by encouraging the use of domestic CNC machine tools for ordering and supporting domestic machine tools on major projects. Such measures encourage the development of high-end CNC machine tools; considering the current domestic and international gaps, the import substitution space is huge. Industry analysts believe that the main demand for machine tools comes from fixed asset investment in the downstream equipment manufacturing industry. The rapid development of China's automotive, aerospace, defense, military, shipbuilding, power equipment, rail transit equipment, engineering machinery, molds, electronic information equipment and other fields has brought momentum to the machine tool industry. In the "Twelfth Five-Year Plan" and in the longer term, China will carry out large-scale and deep-level industrial restructuring, which will bring huge opportunities to the machine tool industry, especially high-end CNC machine tools. As early as the "Eleventh Five-Year Plan" period, China's equipment manufacturing industry has made remarkable achievements. As an important link in the technological progress and industrial upgrading of the equipment manufacturing industry, the machine tool industry overcomes various unfavorable factors such as the impact of the international financial crisis, adheres to independent innovation and scientific and technological progress, and the overall technical level of the industry has been significantly improved, making for the steady and rapid development of China's economy. Important contribution. Facing the new situation and new tasks, analysts believe that the machine tool industry should focus on four aspects: first, speed up the optimization and upgrading of industrial structure, and focus on improving the quality and efficiency of development; second, we must attach great importance to personnel training and effectively improve the ability of independent innovation. The third is to promote the integration of the two, focusing on improving management and product quality; the fourth is to improve quality and service awareness and improve brand innovation. As the downstream industry of the machine tool industry, the aerospace industry, such as aviation, aerospace, ships, weapons, etc., will carry out large-scale and deep-level structural adjustments in the next few years and even longer, bringing huge business opportunities to the machine tool industry. At the same time, the machine tool products will also be updated and higher in terms of accuracy, efficiency, reliability, energy saving and environmental protection. During the "Twelfth Five-Year Plan" period, China must concentrate resources and energy to develop a high-tech aviation industry represented by large aircraft. In the field of modern aviation advanced manufacturing technology, there is an obvious interdependence of "first generation products, first generation technology, first generation tooling and equipment", which determines the important position of major aviation technology equipment in the development and production of modern aviation model products. The high performance, specialization, precision, high efficiency, and reliability brought about by this have become the main features of aerospace product manufacturing equipment. According to the survey results, from the research and development expenses of the large aircraft in the early stage to the production capacity construction, and finally to the market, the relevant investment will exceed 200 billion yuan. From the perspective of the aviation industry, its investment scale will be very large, and it will certainly absorb a large number of high-quality machine tools to serve it. It also challenges the development of the machine tool industry and provides a rare opportunity for development.
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
