Product Description
CPS18635H、CPS18350H
Temperature-Compensated Recessed Diaphragm Ceramic Piezoresistive Sensor Core
The CPS18635H series ceramic pressure sensor core utilizes refined alumina ceramic bases combined with high-stability sensitive materials, crafted through processes like screen printing, high-temperature sintering, and laser trimming.
The CPS18635H dimensions are φ18mm*6.35mm, and its unique circuit design significantly enhances product reliability. The sensitive component integrates a temperature compensation circuit, which is laser-trimmed to ensure that within the standard operating range (-20°C to 85°C), the internal bridge's temperature drift signal is nearly zero (≤0.02% FS/°C), substantially reducing the temperature compensation calibration work required during sensor production.
Ceramic materials offer excellent thermal stability and creep resistance, with an operating temperature range up to -40°C to 150°C, and they demonstrate exceptional long-term stability.
The corrosion resistance of ceramics provides significant advantages in fields like refrigeration, chemical processing, pharmaceuticals, and environmental protection, gradually replacing common diffused silicon pressure sensors.
With a very high cost-performance ratio, the temperature-compensated ceramic piezoresistive sensor core has become a preferred choice for pressure sensing elements in Internet of Things (IoT) applications, widely used for pressure measurement in media such as air, water, and oil. It is extensively applied in fields such as automotive, air compressors, fire protection piping, industrial applications, and household appliances. Our company can customize pressure-sensitive cores in various shapes and sizes according to customer requirements.
