Product Overview
The CYB-S250 ultra-high/ultra-low temperature nanofilm pressure sensor is a high-performance pressure sensor manufactured using our company’s independently developed high-performance nanofilm pressure sensor core, through processes including precise resistance adjustment, laser welding, and fatigue and high- and low-temperature aging tests.
Product Features
● New sensitive material technology, fabricated using internationally advanced nano-film deposition processes and micro-machining techniques.
● It is unaffected by creep, hysteresis, and aging defects introduced by the conventional bonding process used for metal foil strain gauges, ensuring excellent long-term stability and high operational reliability.
● It features excellent temperature characteristics, addressing the issues of large temperature errors and a narrow operating temperature range caused by the absence of PN junctions.
● High-quality stainless steel elastic diaphragm material with excellent media compatibility and strong corrosion resistance. No isolation diaphragm required—no need to fill with oil or liquid.
● High stability: The pressure sensor, after undergoing 10 million pressure cycles, exhibits a drift of ≤±0.1% FS per year.
● At high operating temperatures, it simultaneously features high stability and extremely low zero-point temperature drift.
● Vibration-resistant and shock-resistant, compact in size and lightweight.CYB-S250
