Component Identification
Voltage-free insulated O2 sensors are used.
The active sensor ceramic consists of a gas-permeable ceramic body manufactured from zirconium dioxide. A protective tube with several slots protects
the ceramic body from mechanical stresses and from temperature jumps.
They are connected electrically by means of a 4-pin connector.
Advantages of planar sensor compared to finger sensor:
^
Stable control characteristic
^
Reduced overall size
^
Quick start (control readiness < 10 s)
^
Reduced heating capacity at operating temperature(< 7 W)
^
Increased temperature resistance.
