O2 sensor design - GF07.04-P-4103-03M
Oxygen planar sensor
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.
