ABB Endura AZ20 Oxygen Monitor Combustion Gas Analysis Transmitter

Advanced diagnostics, in accordance with NAMUR NE107.

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 100 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.

2 Relay outputs and a traditional analog output are fitted as

standard, with the option of adding a second analog output or 2

digital inputs/outputs (I/O).

The Endura AZ20 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.
