O2 measurement with Lambda probe
For applications where an oxygen measurement with particular attention to costs is required, a lambda probe derived from the automotive sector is normally used.
Ascon Tecnologic has developed a management and conversion board for the Bosch LSU 4.9 lambda probe.
The board is necessary for the operation of the probe and returns a linearized 4/20 mA analog signal proportional to the set scale range.
Simple and reliable solution suitable for small boilers.
