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.
