CYBERSEN APS18635DG010P

Ceramics is a material featuring high elasticity, corrosion resistance, wear resistance, and resistance to impact and vibration, with excellent thermal stability, anti-creep performance, an operating temperature range of up to -40~125℃, and good long-term stability. The APS18635 (APS18350) series ceramic pressure sensor die is fabricated on a refined aluminum oxide (Al₂O₃) ceramic substrate combined with high-stability sensing materials, processed through screen printing, high-temperature sintering, and laser resistance trimming. The APS18635 series measures Φ18mm×6.35mm (APS18350: Φ18mm×3.50mm). The sensor employs a standard Wheatstone bridge integrated with a zero-offset compensation circuit to enhance long-term reliability. The sensing element incorporates an internal linear temperature compensation circuit. After online high/low temperature testing and laser dynamic trimming for each unit, the internal bridge zero-point temperature drift signal approaches zero (≤±0.015%FS/℃) within the range of -20℃~85℃, significantly reducing the temperature compensation calibration workload during downstream pressure transmitter production. The zero-drift ceramic piezoresistive sensor die offers an excellent cost-performance ratio and is the preferred pressure sensing component for IoT applications. It is widely used for pressure measurement of media such as air, water, and oil, with broad applications in automotive, air compressors, fire protection piping, industrial, and home appliance sectors. Its corrosion resistance provides advantages in refrigeration, chemical, pharmaceutical, and environmental protection fields, where it is progressively replacing conventional pressure sensors such as diffused silicon types.
