Fuji Electric ZFK8 oxygen sensors work in conjunction with Fuji Electric ZKM converters to form the Zirconia Oxygen Analyzer. Using a direct insertion design with zirconium oxide sensing technology, the ZFK8 sensors provide accurate measurement of oxygen concentrations in combustion exhaust gas of industrial boilers or furnaces.
The ZFK8 sensor includes a flow tube which is inserted directly into the gas and directs gas to the sensor for measurement. Flow tubes are available for general purpose applications, corrosive gases or equipped with a blow-down nozzle. Tube lengths from 300 to 1000mm are available. Since the flow tube is separate from the sensor, replacing the filter is quick and easy.
The ZFK8 sensor includes a calibration gas inlet as well as an optional reference air inlet. Diagnostics and recovery functions for the ZFK8 sensor is performed by the ZKM converter.
