CP104 Piezoresistive Ceramic Pressure Sensor Core (C-Module / 4-Pad 8x11)
Standard C-Module Form Factor | Optimized 4-Corner Pad Geometry | 96% Al2O3 Substrate | Robust IndustrialOEM Solution
Product Description & Architectural Design：
* The CP104 (CP-104 Series) is a heavy-duty piezoresistive pressure cell engineered around the industry-standard C-module architectural footprint, featuring a 4-corner solder pad arrangement (8x11 specification). Designed specifically for quick alignment and secure soldering in compact electronic housings, the CP104 streamlines high-volume OEM assembly.
* Formed from a ultra-durable 96% Alumina (Al2O3) ceramic body, the sensing element utilizes thick-film screen printing to integrate a precise Wheatstone bridge directly on the reverse side of the pressure diaphragm. The front face remains unshielded to maintain direct contact with liquids or gases. Leveraging the natural chemical inertness of $96Al2O3, the sensor requires no external isolation barriers or internal filling fluids; it seals directly into transmitter bodies via a standard elastomeric O-ring.
* Refined through OULD’s extensive industrial application background, the CP104 combines high-grade imported conductive inks with full-process automated laser resistor trimming. This delivers outstanding signal repeatability, ultra-low hysteresis, and high linearity across demanding thermal and pressure environments.
