RS186 2Bar Flat Diaphragm Ceramic Piezoresistive Sensor Core
The RS186 temperature-compensated flat diaphragm ceramic pressure sensor core utilizes a refined alumina ceramic base, combined with a highly stable sensing material, and is manufactured through processes such as screen printing, high-temperature sintering, and laser trimming.
The RS186 has dimensions of φ18mm*6.17mm/φ18mm*3.17mm. Its unique circuit design significantly improves product reliability. The sensing element integrates a temperature compensation circuit, which is laser-etched, ensuring that the internal bridge temperature drift signal is close to zero (≤0.02% FS/℃) within the normal operating range (-20℃ to 85℃), greatly reducing the temperature compensation calibration work required during pressure sensor production.
Ceramic possesses excellent thermal stability and creep resistance, with an operating temperature range of -40℃ to 135℃, exhibiting excellent long-term stability.
The corrosion resistance of ceramic gives it significant advantages in refrigeration, chemical, pharmaceutical, and environmental protection fields, and it is gradually replacing common diffused silicon pressure sensors.
Temperature-compensated ceramic piezoresistive sensor cores have become the preferred pressure sensing element in IoT applications due to their extremely high cost-effectiveness, and are widely used for pressure measurement of media such as air, water, and oil. They are widely used in automobiles, air compressors, fire hoses, industrial and home appliances, and other fields. Our company can customize pressure-sensitive cores of various shapes and sizes according to customer needs.
