activepassiveflue gas

Separate electronics for harsh environmental conditions: In-situ zirconium oxide probe for direct and continuous measurement of the percentage of residual oxygen in the combustion fumes, in harsh environmental conditions where high temperatures and/or vibrations could damage the electronics on board. Equipped with separate management electronics, it is able to directly return a linearized 4 … 20 mA signal with active or passive output selectable by jumpers. The probe is supplied complete with connection cable with the separate unit. The main functions of the electronic board are: • Sensor/heater management; • Setting the scale range; • Calibration; • Adjustment of the output signal.
