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).
