Analysing air pollution is the first step toward preserving a clean atmospheric environment. FUJI developed the first infra-red gas analyser in Japan to use mass-flow sensors. Since then, we have supplied customers with various types of gas analysers to support environmental preservation and control efforts. These efforts include measurements of atmospheric pollution and detection of low density of SOx and NOx, generated by incinerating facilities and boilers. FUJI's gas analysers are commonly used to monitor the atmosphere to help maintain a cleaner natural environment.

Fuji Electric ZKM In-situ Zirconia Oxygen Analyser

This oxygen analyser is used to continuously measure oxygen concentration in combustible exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion control and management. The analyser system is comprised of the detector and converter coupled together as a complete system. Detector setting configuration includes the detector flow tube and zirconia detecting sensor. The flow tube is inserted directly into the gas and directs gas to the sensor for measurement. The converter (ZKM) is comprised of the signal processor, input/output and communications, display and system controls. The converter is equipped with advanced functionality such as performing the sensor diagnostics and sensor recovery function, so the detector can be used within long term stability.

Features

• Gas sampling device is unnecessary
  For quick response, insert the detector directly into the flue. Gas sampling functions such as a gas aspirator and a dehumidifier are not required.
• Easy maintenance
  The sensor is equipped with a detector and is easy to replace. By separating the detector and the flow guide tube, filter replacement is made easy.
• More reliable than sensor diagnosis, sensor recoverable function
  Depending on the concentration of the measured gas, the power of the sensor may deteriorate. The equipment includes sensor recovery function electronically, checking the deterioration status of the sensor, thereby giving high reliability and long-lasting stability.
• Safe and secure
  The system detects thermocouple break for heater control on the sensor side. The analyser features the safety functions of either isolating power supply to the detector, or isolating power via external contact input.
• Easy operation
  The operation and settings for the converter can be performed via the front panel.
