Deficiencies of the pressure sensor

With the development of science and technology , there is a certain pressure Crankshaft Positioning Sensor technology breakthrough in the application of increasingly widespread . But there are still many shortcomings. 1 on the basis of poor reliability of the product and manufacturing process technology research is not enough, some impact on the reliability of key technologies, such as precision machining technology, sealing technology , welding technology has not yet been well understood , which is leading products, especially the high-end product performance is not the main reason for stability and reliability . The reliability of existing national indicators of high-end products compared with foreign products , largely to a difference of 1-2 orders of magnitude. (2) product performance and functionality behind the existing domestic products in the measurement accuracy with the foreign products on an order of magnitude difference . Functionally, the current foreign products have a very high degree of intelligence . They are by the original digital information processing , better eliminate the external interference on the impact of information , thereby improving the environmental resistance of the product and measurement authenticity . The existing domestic products is still relatively low degree of intelligence . In addition, the product of the network in foreign countries has entered the practical stage , but China is basically still in its infancy . 3 Auto Temperature Sensor product technology refresh cycle is slow, the current foreign product update cycle in about 2-3 years. New technologies often can advance to reserve ten years. In China, companies often achieved through the introduction of foreign technology generation product updates , after the introduction of digestion and absorption is not well in the new product development outcomes little originality . Some adopt new principles of product in China is still in a blank state . Research institutes in the tracking of new technology , there was an achievement , but the combination of product and business oriented rather difficult. 4 Lack of developed for the use of specific solutions . Abroad in recent years, the development trend of Engine Coolant Sensor is the development or application object associated with tightly integrated software products and, ultimately, to provide users with personalized solutions.
