Description
Lambda sensor OZA685-WW1 NGK
Biomass sensor
The zirconium element is a so-called solid-state electrolyte.
The core of this probe is a hollow, finger-shaped ceramic.
In order to reach the desired operating temperature, a heater integrated into the element is switched on. Depending on the residual oxygen content in the exhaust gas, a high or low electrical voltage is generated in a complex process.
protective tube
The metal protective tube protects the probe element from solids and dust in the exhaust gas
Heater
An integrated heater ensures that the probe element reaches the required operating temperature very quickly and that a constant mV signal is given after just a few minutes.
Ceramic holder
The ceramic holder holds the probe element and protects it from vibrations.
sealing ring
The sealing ring ensures a tight fit between the lambda sensor and the threaded sleeve.
Hex
The probe is screwed in using the hexagon. Pay attention to the appropriate tightening torque.
Seal
To prevent moisture from penetrating the sensor, the cables are routed to the outside through a rubber seal. This rubber seal is pressed over the sensor housing.
Heater connection
The lambda sensor heater is supplied with power via these two white connections.
Probe mass
This gray line establishes the ground connection to the electronics.
Sensor signal
The probe signal is routed to the electronics via this black cable.
