Overview / system dimensions
The Endura AZ40 combustion gas analyzer continuously
samples and analyzes combustion waste gases for both
oxygen and carbon monoxide equivalent (COe).
The analyzer has 4 main assemblies:
— transmitter (controller / display unit), see Fig. 2
— sensor assembly (housing a zirconia-based oxygen sensor,
catalytic COe sensor and an air powered aspirator),
see Fig. 3
— smart sensor electronics (part of the sensor assembly),
see Fig. 3
— probe / filter assembly, see Fig. 3
The analyzer uses a close-coupled sampling system where the
sensor assembly is mounted directly against the process wall.
The sample is filtered and drawn through the sensor assembly
by the air powered aspirator.
This combination of a short sample path and pumped sample
provides a very rapid response to changing gas concentrations.
The gas sample is held above the sample dew point to provide
analysis on a 'wet' basis and prevent acid gases from
condensing in the sample path.Thermocouple inputs for
process temperature measurement enable calculations of
combustion efficiency.
