[Stoves] Oxygen sensors

[Frans Peeters]

Dear experimenters,

 

   The Siemens  LAMBDA sensor you will find it cheaper as” car spare part “.
330 $  . 

Or Car dismantling sales “,used patrs “ 30 $

Industrial chimney Zirconium  oxygen sensors cost  5000 $ .

I have tested mine with oscilloscope into the car .   It is 1Volt chopper
signal .,rectangular  to the car’s controller .

4 wire , 2 are heater 12 V 1 Amp  .

In” Elector “Magasine you find  a readout circuit and print to build  it
yourself .

>From Siemens you get detail info how the detector is made .

For other labo experiments you put a  PT100  sensor together to read the
temperature  700° C .

It is less cumbersome than FIGARO’s in BLACK boxes . Frank .

 

Greetings

Frans
