Maximum Temperature for the Lambda Sensor

Post by sebjos » 19 Dec 2022 08:55

Hi!

I couldn't find the info in the forum. I plan to use the whole lambda sensor solution to control the O2 ratio in a furnace. What is the max temperature the sensor can be exposed to (based on that, i might install a pipe to cool a fraction of the furnace air for the measurement).

Thanks in advance and kind Regards

Sebastien

Hello Sebastien,

The maximum temperatures can be found in the sensor data sheet .

Exhaust gas temperature < 930°C range (operating)
Exhaust gas temperature < 1,030°C range (max.) for short time
Hexagon temperature < 600°C
Wire and protective sleeve < 250°C temperature
Connector temperature < 140°C

Hope it helps.
Best Regards,
