AV550G-A-A1-E-2-E轉換器
Overview
Zirconia oxygen analyzers are used in
combustion facilities to measure the ? ue gas
oxygen concentration. Boiler operators use the
oxygen measurement to optimize fuel usage
minimize atmospheric emissions and reduce energy
consumption.
A multiple point oxygen measurement system is
required for situations when gas strati? cation in the
? ue duct affects combustion control. The AV550G
Averaging Converter can accept inputs from up to
eight zirconia oxygen detectors. It sends output
signals for the individual as well as averages of
multiple oxygen concentrations. A robust multipoint
converter reduces installation and maintenance costs.
A large 5.7-inch color LCD shows various
measurement setup calibration and trend screens.
Its intuitive touch screen is easy to read and
makes set up and maintenance simple. Other
standard features include new self-diagnostics and
a hot swap function that allows a desired probe
to be disconnected/reconnected for inspection or
maintenance just by turning off the power of the
relevant channel.
The AV550G Averaging Converter is ideal for
combustion control in large utility boilers or various
industrial furnaces.
