Fuji Electric infrared gas analysers are designed for process control and continuous measurement of stack emissions.
Their QAL1 certification guarantees high performance and regulatory and normative compliance.
Reliable and precise, their design quality guarantees 24-hour operation in difficult environments such as smoke from industrial chimneys.
Their robustness reduces maintenance costs and increases boiler and equipment availability.
Extractive measurement consists of taking a gas flow from the chimney or the gas pipe via a sampling probe and conveying it to the gas analyser.
The gas is sampled, treated in order to ensure optimal conditions for gas measurement.
The Fuji Electric extractive multigas analyser range consists of non-dispersive 5-gas infrared analysers.
They allow simultaneous and continuous measurement by extraction of 1 to 5 gases from:
simple maintenance
good precision
digital link
automatic calibration
The mass flow meter determines the amount of infrared light absorbed by the measuring cell.
Mass flow meter :
Uses a highly sensitive mass flow meter as a detector.
Simultaneous and continuous measurement of 5 gases:
Outstanding repeatability is assured with accuracy down to ± 0.5% of full scale (FS). For ranges below 50 ppm, repeatability remains outstanding with an accuracy of ± 1% FS.
The analyser maintains precise linearity with a maximum tolerance of ± 1% PE, ensuring constant correlation between measured concentration and actual value.
Zero drift is minimized with a maximum variation of ± 1% FS per week. Even for ranges below 50-200 ppm, zero stability remains remarkable, with a drift of just ± 2% FS.
Scale drift is also kept under control, with a maximum variation of ± 2% PE per week, ensuring consistent measurements.
The analyser displays high reactivity with a fast response time of ≤ 60 seconds to reach 90% of the measured concentration.
SPST-NO and SPDT contact outputs ensure efficient communication with features such as error detection, self-calibration, CO peak alarm, power failure, etc.
Optional RS485 (Modbus®) communication provides network connectivity for easy integration with other systems.
The backlit LCD display provides a clear view of the instantaneous value, the instantaneous corrected O2 value, the average corrected O2 value and the average O2 value.
Compatible with supply voltages from 100 to 240 Vac, 50/60 Hz, the analyser offers optimum flexibility.
With a power consumption of 250 VA,analyser ensures energy-efficient operation.
Dimensions of 483 (W) x 177 (H) x 600 (D) mm and a weight of around 22 kg ensure easy integration in a variety of environments.
Simultaneous and continuous measurement of the concentration of 5 gases:
The analyser guarantees exceptional repeatability, with an accuracy of up to ± 0.5% of full scale (FS). This accuracy remains remarkable even for ranges below 50 ppm, where repeatability reaches ± 1% FS.
The linearity of analyser is maintained with a maximum tolerance of ± 1% PE, guaranteeing a constant correlation between the measured concentration and the actual value.
Zero drift is limited to ± 2% PE per week, ensuring optimum stability. For ranges of 500 ppm or less, zero self-calibration is activated for enhanced accuracy.
Scale drift is controlled to ± 2% PE per week, guaranteeing consistent measurements.
The analyser excels with a fast response time of ≤ 60 seconds to reach 90% of the measured concentration.
SPST-NO and SPDT contact outputs facilitate efficient communication, with functions such as error detection, self-calibration, CO peak alarm, power failure, etc.
Optional RS485 (Modbus®) communication offers seamless network integration with other systems.
The backlit LCD display provides a clear view of the instantaneous value, the corrected instantaneous O2 value, the corrected average O2 value, and the average O2.
Compatible with supply voltages from 100 to 240 Vac, 50/60 Hz, the analyser offers optimum flexibility.
With a power consumption of 100 VA, the analyser ensures energy-saving operation.
With dimensions of 483 (W) x 133 (H) x 418 (D) mm and a weight of 8 kg,analyser is easy to integrate into a variety of environments.
The amount of infrared radiation absorbed in the measuring cell is detected by a micro mass flow meter.
The low-impedance micro mass flowmeter has excellent immunity to interference, and the sensor, with no moving parts, is insensitive to vibration.
ZPA is best suited to the measurement of exhaust gas from refuse incinerators, boilers, and various industrial furnaces.
