XGZP101SB1 oxygen pressure sensor SOP package

XGZP101SB1 Oxygen Pressure Sensor SOP Package is a high-precision piezoresistive silicon pressure sensor designed specifically for medical and industrial applications requiring accurate gaseous media measurement. This surface-mount device utilizes advanced MEMS technology to provide a reliable millivolt output proportional to the applied pressure. Consequently, it excels in environments where small form factors and long-term stability are critical for system performance. The sensor features a unique gel-filling or specialized coating to protect the silicon chip against moisture and corrosive gases like oxygen. Therefore, you can confidently integrate this component into ventilators, oxygen concentrators, and various pneumatic control systems to ensure patient safety and process accuracy. Furthermore, its standardized SOP-6 package simplifies automated assembly for high-volume manufacturing.
