The "Aerospace-Grade CY Series Ultra-Low Temperature Pressure Sensors" independently developed by Qingdao Qingdao ZITN Technology Co., Ltd. Co., Ltd. have been successfully selected into Shandong Province's second batch of "First-Set" electronic products. They have also become the first products in Shandong Province's high-reliability sensor field to receive this certification.
This sensor for extreme environments has overcome the technical challenge of high-precision monitoring for liquid oxygen-methane engines in the extreme temperature range of -196℃ to -163℃ and under a transient temperature variation span of 200℃. It has been applied to "Zhuque-2", the world's first liquid oxygen-methane rocket that successfully entered orbit, and has played an important role in China's first 10-kilometer-level vertical takeoff and landing test of reusable launch vehicles.

This technological breakthrough solves the nonlinear drift problem of traditional sensors under extreme temperature variation conditions, fills the gap in high-precision and high-reliability sensors for transient monitoring in domestic liquid oxygen-methane rocket launch scenarios, provides reliable support for the accurate interpretation of launch conditions of 100-ton-class launch systems, breaks foreign technological monopolies, realizes independent and controllable key components, and holds independent intellectual property rights.

Founded in 2002, Qingdao ZITN Technology Co., Ltd. is a national-level key "little giant" enterprise specializing in segmented markets with high specialization, refinement, differentiation and innovation. It focuses on the development of high-reliability sensors and has won many honors, including the third place in the national finals of the 2nd Innovation and Entrepreneurship Competition and a spot in the "National Top 100 Hard Technology Enterprises". The company has participated in 2 national major science and technology projects, led over 10 provincial and municipal key technology research projects, and undertaken the construction of the Shandong Provincial Engineering Research Center for Intelligent Microsystems and Sensor Technology in Extreme Environments. It is also a Shandong Provincial "One Enterprise, One Technology" R&D Center, with its products widely used in high-end fields such as aerospace.
