passiveoxygenflue gas

Integrated electronics for standard conditions: In-situ zirconium oxide probe for direct and continuous measurement of the percentage of residual oxygen in the combustion fumes. Equipped with management electronics integrated in the head, it is able to directly return a linearized 4 … 20 mA signal with active or passive output selectable via jumpers. The main functions of the electronic board are: • Sensor/heater management; • Setting the scale range; • Calibration; • Adjustment of the output signal.
