Ceramic Flush Diaphragm Pressure Sensor Core with Temperature Compensation for Level Measurement

RS214A Series Flush Diaphragm Ceramic Piezoresistive Sensor Core

The RS214A series flush diaphragm ceramic piezoresistive sensor core uses a meticulously crafted alumina ceramic base, combined with highly stable sensitive materials.
It is refined through processes such as screen printing, high-temperature sintering, and laser trimming.

The RS214A has dimensions of φ21X(4.10-4.77))mm. Its unique circuit design significantly enhances product reliability.
The sensitive element internally integrates a temperature compensation circuit and undergoes laser trimming, ensuring that within the conventional usage range (-20°C to 85°C), the internal bridge temperature drift signal is nearly zero (≤0.02% FS/°C), greatly reducing the temperature compensation calibration required during pressure sensor production.

Ceramic material offers excellent thermal stability and creep resistance, with an operating temperature range up to -40°C to 150°C, demonstrating outstanding long-term stability.

The corrosion resistance of ceramic provides significant advantages in fields such as refrigeration, chemical industry, pharmaceuticals, and environmental protection, gradually replacing the common diffused silicon pressure sensors.

With its high cost-effectiveness, the temperature-compensated ceramic piezoresistive sensor core becomes the preferred choice for pressure sensing elements in IoT applications. It is widely used in measuring the pressure of air, water, oil,
and other media. It has extensive applications in areas such as automotive, air compressors, firefighting water pipes,
industry, and household appliances. We can customize various shapes and sizes of pressure-sensitive cores according to customer requirements.
