Product Information

Zirconia Oxygen Analyzer Converter AV550G

A multiple point oxygen measurement system may be required for situations when gas stratification in the flue 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 display 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.

Features

*	Full color touch screen
*	Special trend graph functions with customer graph configuration
*	Multiple display modes shows average data, single detector or all detector gas concentrations
*	Handles input of up to 8 oxygen detectors
*	“Hot swap” of channel cards so the analyzer remains on line while maintenance is performed
*	Eight 4-20mA outputs for individual detectors.
*	Three 4-20mA outputs for average oxygen concentration outputs.
*	Failed, in calibration, or alarming, detectors are automatically excluded from average calculations.
*	Data of Hi and Low alarm can be excluded
*	Allows contact input, calibration activation, range change and detector performance validation.
*	Remote maintenance using digital communications (HART of FOUNDATION Fieldbus) reduces maintenance costs.
