Precise sensing, safeguarding the skies: Sensor Nobleman aerospace-grade pressure sensors achieve a breakthrough in independent controllability.
2025-12-18
On the test stand where rocket engines’ fiery flames roar forth, and at every instant when spacecraft push beyond their operational limits—precise measurement of pressure parameters directly determines the success or failure of the mission and the safety of human life.
For a long time, high-temperature-resistant, impact-resistant, and ultra-high-precision pressure sensors have been a critical “bottleneck” issue that China’s aerospace industry has urgently needed to overcome. Today, with its completely independent nanofilm sensing technology, SunoMeng Technology has forged reliable “sensory nerves” for China’s major national projects, achieving a fundamental leap—from reliance on imports to self-reliance and controllability.
01 Confronting the Ultimate Challenge: The Core Pain Points of Space Measurement
The aerospace industry has nearly exacting requirements for pressure sensors. Take rocket engines, for example: their sensors must operate reliably over extended periods in high-temperature gas environments reaching 300°C continuously and temporarily exceeding 1,000°C, while also withstanding shocks of up to 5,000g—and all this under extreme conditions while maintaining a measurement accuracy better than 0.05%.
For a long time, high-end pressure sensor technology that can simultaneously meet the above-mentioned comprehensive performance requirements has been monopolized by foreign countries, becoming a critical bottleneck that hinders the independent development of China’s key equipment.
02 Rigorously Tested in Real-World Scenarios: Supporting China’s New Journey in Space Exploration
True technology must withstand the most rigorous real-world testing. In early 2025, SunoMeng’s ultra-high-temperature nanofilm pressure sensors were used in a test run of a certain solid-propellant rocket engine.
After undergoing a full test run involving two exposures to high temperatures of 300℃ (with instantaneous temperatures reaching 1,000℃) and accelerations up to 5,000g, the products still maintained accuracy levels better than 0.04% (with a maximum of 0.02%). All test data have been verified by one of the nation’s leading metrological authorities—the Changre Thermal Primary Metrology Station of the National Defense Science and Technology Industry, whose authority provides the strongest endorsement for the product’s outstanding performance.
Such outstanding performance advantages—combined with its compact size (12 mm in diameter and 40 mm in length) and wide measurement range (with options ranging from 0 to 100 kPa to 300 MPa)—greatly meet the core requirements for high reliability and long service life. This successfully addresses a series of technical challenges in aerospace applications, including high-temperature resistance, small size, and shock resistance of sensors.
03 Technological Breakthroughs: The Core Advantages of Nanofilm
Its ability to operate reliably in such a demanding testing environment stems from SunnoM’s groundbreaking breakthrough in nanofilm technology. Through entirely independent R&D, SunnoM Technology has overcome the material and process bottlenecks that have long hindered the development of high-performance sensors. Creatively employing novel alloy-sensitive functional materials and atomic-layer deposition technology. This enables the thin-film strain resistor and the metallic elastomer to achieve “atomic-level fusion” directly, fundamentally eliminating the creep, hysteresis, and aging issues inherent in conventional manufacturing processes. Brings a revolutionary performance boost to the Sensor Nobleman series of pressure sensor products:
Outstanding product stability: After 10 million pressure cycles, the sensor’s annual drift can be controlled within ≤±0.05%FS, ensuring an exceptionally long service life and extremely high, long-term stability.
Extremely high measurement accuracy: Combining special materials with perfect manufacturing processes, the product’s overall accuracy can reach 0.02%.
Ultra-wide operating temperature range: The product can operate stably across an extreme temperature range from -196℃ to 400℃; some models can even withstand temperatures as high as 1000℃, perfectly meeting the demands of an extremely broad temperature range.
Exceptionally high environmental adaptability: With an integrated structure based on special alloy materials and a novel atomic-layer deposition technology for sensitive materials, this product can confidently handle complex and harsh environments such as intense space radiation, severe corrosion, high overload, and strong impacts.
04 Leading the Future: From Self-Reliance and Controllability to Defining Standards
The successful breakthrough of the Sensor Nobleman’s nanofilm sensing product series carries significance that goes far beyond simply replacing imported products with domestically produced ones. Leveraging its core nanofilm technology—on which Songnongmeng has obtained 40 authorized invention patents in China, the U.S., Russia, the U.K., Japan, Germany, and other countries—Songnongmeng Technology has developed products such as ultra-high-purity pressure sensors, high-precision nuclear-grade pressure transmitters, and ultra-high-temperature, compact oil-drilling pressure sensors. These products have successfully replaced imported alternatives in their respective fields, addressing critical “bottleneck” challenges and becoming the top choice and new industry standard for a wide range of users.
Previously, following evaluation by a panel of academician experts, the Sensor Nobleman nanofilm series products... Overall performance has reached the internationally advanced level, and some indicators have even reached the internationally leading level. This marks that, in the critical field of high-end sensors, China has achieved complete self-reliance and control over core sensing components, firmly securing the “sensing nerve” of this vital national asset in its own hands, thereby ensuring supply-chain security and maintaining initiative in the R&D process.
Based on this foundation, Suno-Meng Technology not only provides China’s aerospace industry with a reliable and independent choice but also leverages its cutting-edge technological capabilities to actively participate in the global competition for high-end sensing technologies. Looking ahead, the company will continue to deepen its expertise in nanofilm sensing technology, steadfastly promoting domestic production and independent innovation, and contributing more precise and resilient sensing solutions to the development of China’s aerospace, major engineering equipment, and related projects.
