YOKOGAWA Multi Channel Oxygen Analyzer System ZR22/AV550G

Zirconia Oxygen Probe/Sensor - ZR22

The industry leading ZR22 in-situ type Zirconia detector provides dependable and accurate oxygen measurement. 

Available in lengths from 15 cm to 5.4 meters, the ZR22 can be used in process temperatures up to 700ºC (up to 1871ºC with 

our close-coupled extractive adapter ZR22P), and pressurized ducts up to 2.5 bar with the pressure compensating option.

The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. 

This reduces maintenance costs and allows faster measurement response to changes in the process. 

The new probe's modular design incorporates a rebuildable heater and thermocouple assembly, 

the industry standard field replacable Yokogawa Zirconia cell, and removable reference and calibration lines to create 

an oxygen measurement product designed for simple, quick and low-cost field maintenance.

* Rebuildable, field maintainable design

* Proven Zirconia sensor technology

* Can be used in pressurized ducts up to 2.5 bar, 700°C (up to 1871ºC with ZR22P adapter)

* Optional filters or flame arrestors

* Multiple flange size options

* Hazardous area probe available (ZR22S)

Multi Channel Zirconia Oxygen Analyzer - AV550G

The O2mation, model AV550, averaging oxygen analyzer was designed with a focus on practical performance. 

Yokogawa has refined our expertise in the combustion oxygen business into this new and creative product. 

It is packed with features designed to minimize plant down time and technical support for the oxygen measurement. 

A multiple point oxygen measurement system may be required for situations when gas stratification in the flue duct affects combustion control. 

The AV550G averaging analyzer is ideal for combustion control in large utility boilers or various industrial furnaces.

* Can accept inputs from up to eight ZR22 detectors

* Sends both individual and averaged sensor outputs

* Multipoint analyzer reduces installation and maintenance costs

* Large 5.7-inch color LCD display shows various measurement, setup, calibration, and trend screens

* Intuitive touchscreen is easy to read and simplifies setup and maintenance

* Individual channel cards can be "hot swapped" 

* 4-20 mA standard outputs with HART or Foundation Fieldbus

Model AV550G Zirconia Oxygen Analyzer Averaging Converter

Zirconia oxygen analyzers are used in combustion facilities to measure the flue 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 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 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.
