2 Introduction The Endura AZ is the latest in a long line of high-quality, combustion gas analyzers from ABB. The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted in the flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion control optimization and emissions monitoring. Lengths up to 4. m (. ft.) A wide range of probe insertion lengths from.5 to 4. m (.7 to. ft.) enable installation to the optimum measuring point for accurate oxygen measurement within the duct; even in the largest flue gas ducts and stacks. A comprehensive range of mounting flanges provide simple installation when plant-wide standard flanges are required or when replacing existing probes. The transmitter can be probe- or remote-mounted at distances of up to m (8 ft.), thus providing versatile system options for all applications. The probe-mounted transmitter option provides the lowest cost of installation. However, the remote-mounted transmitter provides flexibility when the operationally ideal probe location does not provide easy access for the user. Advanced Design Designed and manufactured to exacting standards, the Endura AZ ensures long periods of trouble-free operation in even the most arduous of applications. The operating process temperature of up to 8 C (47 F) extends system suitability into previously impossible applications and enables optimum probe location within the process. The modular design, with reduced component count, improves the robustness and reliability of the system and simplifies routine maintenance and servicing. Complete traceability ensures only the highest quality materials are used in the analyzer's construction and rigorous manufacturing, inspection and testing procedures (to international standard ISO 9) result in a monitor of superior quality with prolonged probe life. and Remote-mounted Transmitter and -mounted Transmitter Modular Construction

3 Easy Cell Release The Endura AZ probe has retained the easy-access cell arrangement of the previous generation ZFG probes. Cell replacement can be performed on-site using basic hand tools; even after long periods of high temperature operation where screw threads have 'seized' and can no longer be released. Kits containing all the parts needed to complete maintenance are available from ABB to ensure a technician can perform services quickly, efficiently and at minimum cost. Unique Integrated Automatic Calibration The all new Endura AZ automatic calibration system eliminates the need for the expensive ancillary equipment required for automatic calibration on traditional flue gas oxygen analyzer systems. ABB s fully integrated, automatic calibration feature controls the test gas sequence and detects test gas availability, eliminating incorrect calibrations due to loss of test gas. Proven Cell Design ABB's metallurgically bonded, multi-layer electrode technology increases the cell's resistance to sulphurous and reducing atmospheres and high temperature operation. This extends the life-cycle of the cell in the most arduous applications such as sulphur recovery processes, crematoria and industrial/clinical waste incineration. Zirconia Cell Flow Rate Control using Flow Restrictors The flow rates of test gas and reference air are important to the accurate operation of Zirconia-based oxygen analyzers and, traditionally, control has been achieved using ancillary flowmeters and flow control valves. The Endura AZ offers a new approach with the inclusion of optional flow restrictors. These are fitted within the probe to control the flow rate of the reference air and test gasses, removing the need for additional flowmeters fitted with flow control valves. This innovative approach enables the gasses to be controlled by pressure only. Bar (5 psi) is applied directly to the probe s gas ports and the correct flow rate is then set by the flow restrictors. Advanced Automatic Calibration Facility Integrated automatic calibration secures the oxygen measurement, providing complete confidence in the analyzer's performance. Long-term operation without technician intervention minimizes operating costs, total cost-of-ownership, optimizes system accuracy and contributes to the CEMS (Continuous Emmissions Monitoring Compliance). A significant proportion of service visits to an analyzer result in 'no fault found'. Endura AZ's high-quality manufacture, advanced diagnostics and fully-integrated, automatic calibration is targeted at reducing this wasted effort and cost.

4 Advanced Transmitter The Endura AZ transmitter incorporates the most up-to-date design and technology available today. ABB's universal human/machine interface (HMI) with its large, clear, backlit graphical display, 'through-the-glass' control and intuitive menu structure simplifies transmitter configuration and operation. The user-friendly interface enables fast, easy data entry for all parameters and the 'Easy Setup' menu speeds and simplifies system commissioning. Advanced diagnostics, in accordance with NAMUR NE7, classify alarms and warnings as 'Maintenance Required', 'Check Function', 'Failure' and 'Out-of-Specification'. Cell performance is monitored by the transmitter; indicators such as cell impedance, rate-of-response to test gasses and changes in calibration offset/factor are recorded and analyzed. The current cell 'quality' is displayed by the transmitter as a visual indication of the measurement confidence; providing the operator all the information required to keep the monitor operating at peak performance. The Performance Log holds up to time-stamped events. When the log is full, the oldest data is overwritten by new entries. The log contains details of measurements and coefficients for all calibrations and accuracy checks. Relay outputs and a traditional analog output are fitted as standard, with the option of adding a second analog output or digital inputs/outputs (I/O). The Endura AZ transmitter is equipped with HART communication as standard, supported by a full Device Type Manager (DTM) to enable remote access to the analyzer through a user-friendly graphical interface. The DTM provides full access to the transmitter setup, logged data and diagnostics information as well as live data. The IrDA standard infrared communication port can also be used with the DTM to upload and download device configurations. In addition, it enables data logged values and diagnostics to be viewed on a hyperterminal interface or a PC. The device s firmware can also be upgraded using this port.
