CP310 Ultra-Thin Flat Diaphragm Ceramic Pressure Sensor Core
Ultra-Slim 3mm Profile | 18mm Standard Outer Diameter | 96% Al2O3 Thick-Film Cell | High-Precision OEM Solution
Product Description & Architectural Design：
* The CP310 (CP-310 Series) is a specialized ultra-thin piezoresistive ceramic pressure core engineered for high-density sensor assemblies and space-critical transmitter bodies. Constructed on a high-purity 96% Alumina (Al2O3) substrate, the CP310 features an optimized flat-diaphragm architecture with physical dimensions of 18mm in diameter and only 3mm (±0.1mm) in thickness.
* Using precision thick-film screen printing, a robust Wheatstone bridge is applied directly to the reverse side of the ceramic diaphragm, while the front face remains unshielded to maintain direct contact with the measured fluid or gas. The natural chemical inertness of 96%Al2O3 eliminates the need for secondary protective coatings, internal oil-filled cavities, or metallic isolation membranes. The core seals directly into transmitter housings via standard elastomeric O-rings, streamlining mechanical assembly.
* Backed by years of thick-film manufacturing experience from OULD, the CP310 incorporates high-grade imported conductive pastes and 100% automated laser resistor trimming. This ensures exceptional signal repeatability, low hysteresis, high full-span linearity, and long-term signal stability across wide temperature ranges.
Core Performance Advantages：
1，Ultra-Slim Low-Profile Form Factor: With a thickness of just 3mm (±0.1mm) and an 18mm outer diameter, it allows maximum flexibility for compact instrument housing designs.
2，Flat Diaphragm Direct-Media Contact: Smooth flush-diaphragm design prevents media accumulation and simplifies cleaning in fluid lines.
3，High Full-Scale Linearity & Low Hysteresis: Optimized bridge pattern combined with automated laser trimming ensures predictable, high-precision proportional output.
4，Superior Chemical & Burst Pressure Resistance: Solid 96% (Al2O3) ceramic structure withstands corrosive liquids, mild acids, and high overload pressure spikes.
5，Broad Thermal Range & Integrated Compensation: Active thick-film compensation minimizes zero and sensitivity drift under ambient thermal variations.
6，Long-Term Operational Stability: Inherently resistant to mechanical fatigue and thermal creep, ensuring multi-year measurement consistency.
7，Simple & Leak-Proof Installation: O-ring radial or axial sealing simplifies custom enclosure design and reduces assembly labor costs.
