ABB Endura AZ20 combustion gas analyser

Manufactured using a ceramic-to-steel bonding process, the Endura AZ20 combustion gas analyser offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperature, as well as offering a gas tight bond throughout its operating temperature range.

Featuring a revised sensor design and an increased choice of probe lengths up to 4 m, the analyser expands the company’s range of high-temperature applications up to 800°C. The analyser benefits from a cell processing technique that bonds the multi-layered platinum electrode to the zirconia. This means that the analyser can be used in applications subject to sulphurous and reducing atmospheres such as sulphur recovery processes, crematoria and industrial and clinical waste incineration.

‘Through-the-glass’ HMI control technology provides a local operator interface for inputting short, quick data for all user specific parameters without removing the transmitter cover. As a HART-enabled device, the analyser offers the ability for operators to perform online modification and monitoring of parameters.

Improved process control is achieved by the positioning of the zirconium oxide measuring sensor at the tip of the probe, which is then inserted into the flue duct.

Integrated advanced calibration technology automatically controls both the test gas flow rate and test gas sequences during calibration testing. This eliminates the need for expensive ancillary equipment typically needed for traditional flue gas oxygen analyser systems and prevents incorrect calibrations caused by the loss of test gas.
