Problems to be solved in the localization of fire pressure sensors

(Summary description)  Fire pressure sensors are the most widely used products in modern industrial production, and they are widely used in many industries. However, a large part of the domestic demand for pressure sensors still relies on imports, especially for precision pressure measurement occasions. In the past few years, domestic manufacturers have also continued to improve their technology, product performance has been improved, and the phenomenon of uneven quality has also appeared. On the other hand, it has also led to a reduction in the price of foreign products, but they are still very expensive compared with domestic products.     The pressure sensor structure mainly adopts piezoresistive and capacitive. Piezoresistive sensors are the most widely used. Most domestic manufacturers rely on imported piezoresistive sensors to design and manufacture domestic transmitters. This is also a good way, because piezoresistive technology is relatively mature, and it is more suitable for localized development. Its disadvantage is that it is relatively affected by environmental factors such as temperature and humidity. The static pressure characteristics depend on the manufacturing process level, and the domestic process level also needs to be improved. Based on these two points, the accuracy and stability of domestic piezoresistive sensors are still lower than those of foreign countries. Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil well, electric power, ships, machine tools , Pipelines and many other industries, the following briefly introduces some common sensor principles and their applications.     The advantages of capacitive pressure sensors are high measurement accuracy and long-term stability. However, it is more dependent on the production process and processing difficulty. Some process technologies are still blocked by foreign countries. Therefore, if you want to produce excellent capacitive pressure Sensors and process technology must be addressed first. Domestic manufacturers are also groping step by step. Fortunately, some companies have developed silicon capacitive sensors. The accuracy and static pressure characteristics are not very different from those of foreign countries, but the stability is still worse. In addition, domestic capacitive sensors still have a big gap in the development of high differential pressure and micro differential pressure specifications.
