Flush Diaphragm Ceramic Piezoresistive Sensor Core for Extensive Temperature Compensation Calibration
Main Features
RS214A Series Flush Diaphragm Ceramic Piezoresistive Sensor Core
The RS214A series flush diaphragm ceramic piezoresistive sensor core is crafted from high-quality alumina ceramic, integrated with stable sensitive materials. It undergoes advanced manufacturing processes, including screen printing, high-temperature sintering, and laser trimming.
- Dimensions: φ21 x (4.10-4.77) mm.
- Enhanced Reliability: Its unique circuit design significantly boosts product reliability.
- Temperature Compensation: The sensitive element includes an internal temperature compensation circuit, which is laser-trimmed to ensure minimal temperature drift (≤0.02% FS/°C) within the standard operating range (-20°C to 85°C). This feature greatly reduces the need for extensive temperature compensation calibration during production.
Exceptional Performance
- Thermal Stability and Creep Resistance: The ceramic material offers remarkable thermal stability and creep resistance, with an operational temperature range extending from -40°C to 150°C, ensuring long-term reliability.
- Corrosion Resistance: The ceramic’s properties provide significant advantages in industries like refrigeration, chemicals, pharmaceuticals, and environmental protection, gradually replacing traditional diffused silicon pressure sensors.
Cost-Effective Solution for IoT
With excellent cost-effectiveness, the temperature-compensated ceramic piezoresistive sensor core is the preferred option for pressure sensing in IoT applications. It is widely utilized for measuring air, water, oil, and other media, with applications spanning automotive, air compressors, firefighting systems, industrial uses, and household appliances. Custom shapes and sizes of pressure-sensitive cores can be tailored to meet specific customer needs.
