Core Structure and Operating Principle (Basics of Understanding the Process)

First, we need to understand the core task of an oxygen sensor: detecting the oxygen concentration in the exhaust gas and generating a corresponding electrical signal.

Core Component: A zirconium dioxide (ZrO₂) ceramic tube/plate, which allows oxygen ions to pass through at high temperatures, forming an "oxygen concentration cell."

Key Structure:

Zirconium dioxide ceramic body: Typically in the form of a test tube or flat plate.

Platinum Electrode: A porous platinum layer sintered onto the inner and outer surfaces of the ceramic body, providing both electrical conductivity and gas permeability.

Heater: A built-in ceramic heating rod that quickly (typically within 30 seconds) raises the sensor to operating temperature (approximately 600-800°C).

Metal Housing: A housing with ventilation holes for mechanical attachment and physical protection.

Multi-layered Protective Layer: Includes a porous ceramic protective layer (for corrosion and erosion protection) and a dense isolation layer (to prevent electrode poisoning).
