Product Description
Flush Diaphragm Pressure Sensor Ceramic Pressure Sensor Core For Level Measurement
RS214A Series Flush Diaphragm Ceramic Piezoresistive Sensor Core
The RS214A series flush diaphragm ceramic piezoresistive sensor core features a meticulously crafted alumina ceramic base combined with highly stable sensitive materials. Refined through advanced processes including screen printing, high-temperature sintering, and laser trimming, this sensor core delivers exceptional performance and reliability.
Key Features
- Patented circuit layout design
- Unique structural design
- Ultra-high overload and burst pressure, suitable for high-impact pressure scenarios
- Wide temperature range with broad applicability
- High-elasticity diaphragm enhances sensitivity and meets high-precision measurement requirements
- Supports precise data acquisition
The RS214A has dimensions of φ21×(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 minimal internal bridge temperature drift signal (≤0.02% FS/°C) within the conventional usage range (-20°C to 85°C), greatly reducing temperature compensation calibration requirements 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 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, with extensive applications in automotive, air compressors, firefighting water pipes, industrial equipment, and household appliances. We can customize various shapes and sizes of pressure-sensitive cores according to customer requirements.
