Product Description
RS186 1Bar flat diaphragm ceramic piezoresistive sensor core
The RS186 temperature-compensated flat diaphragm ceramic pressure sensor core is made of a refined alumina ceramic base, combined with a highly stable sensitive material, and is refined through processes such as screen printing, high-tem
The RS186 has dimensions of φ18mm*6.17mm, and its unique circuit design significantly improves product reliability. The sensing element integrates a temperature compensation circuit and is laser-etched, making the internal bridge temperature drift signal 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.
Ceramics have good thermal stability and creep resistance, with a working temperature range of -40℃ to 135℃, and exhibit excellent long-term stability.
The corrosion resistance of ceramics gives them significant advantages in fields such as refrigeration, chemical industry, medicine and environmental protection, and they are 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.
