[Stoves] Oxygen/Benzin sensor=-LAMBDA SONDE

[frank]

Hi Frans,
I'm trying to understand what you wrote. In a car engine you have BTX vs 
20% O2. With poor combustion you have a lot of BTX and with good 
combustion you have low BTX.  And it seems the response of the sensor  
is calibrated between the two.

But in a wood burning stove we have the O2 but what are we going to use 
as the upper value as it seems its the VOC that the sensor is actually 
reading.(?).  Can we even use this when the upper value changes 
depending on the VOC and with stoves, the VOCs differ in composition? 
and there is no BTX?


Great info as always

Frank
