Key Structural Summary Diagram

Core Sensing Unit: Stable Zirconia Ceramic Tube/Rod + Porous Platinum Electrodes (both inner and outer).

Thermal Management Unit: Features an embedded heating resistor wire and thermocouple to ensure the core operates at a constant high temperature (≈750°C) work point.

Reference Gas System: Designed permeable channels provide an internal reference gas (air) with a constant O2 concentration.

Protective mechanical structure: Corrosion-resistant alloy housing (with diffused holes/slots) + mounted flange/screw.

Electrical Sealing Structure: High-performance ceramic-metal sealing joints ensure electrical isolation, airway separation, and long-term sealing.
