Gas Analyzers

MG8G Paramagnetic Oxygen Analyzer

2009-12-18T01:57:00.002-08:00

The MG8G paramagnetic oxygen analyzer measures the concentration of oxygen based on the factthat a magnet attracts gaseous oxygen. Whereas zirconia oxygen analyzers cannot measure oxygen in flammable gas mixtures, the MG8G can measure oxygen concentration in flammable gas mixtures.

With an appropriate sampling system it can also measure oxygen in high temperature or high pressure process gas mixtures.

The sensor has a totally new architecture for its magnetic proportional flow rate system that has been developed based on our long and field-proven experience. The converter is microprocessor based, providing ease of use and high reliability.

OX400 Low Concentration Zirconia Oxygen Analyzer

2009-12-18T01:57:00.001-08:00

This is the latest oxygen analyzer from Yokogawa, and its development was based on the company's long experience and strong track record with this technology.
A proprietary new thin-film deposition technology was used in the zirconia sensor that creates a molecular bond between the zirconia element and the platinum layer. This prevents separation, enables a reduction in sensor size and ensures a high-speed response and long life.
The OX400 can be used to control and monitor various semiconductor applications, and to control environment, air leakage into inert gas, and other processes.

・	Oxygen concentration control in semiconductor-related diffusion and drying furnaces and in LCD manufacturing processes
・	Oxygen concentration control in solder pot flow and re-flow ovens, and glove boxes used in electronics manufacturing, and in gas production processes
・	Oxygen concentration measurements to prevent dust explosions during powder transfer

AV550G Zirconia Oxygen Averaging Converter

2009-12-18T01:56:00.002-08:00

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.

ZR22S, ZR202S Explosionproof Zirconia Oxygen Analyzers

2009-12-18T01:56:00.001-08:00

Two types are available for an explosionproof direct in situ zirconia oxygen analyzer. Model ZR22S/ZR402G is a separate type which consists of a ZR22S explosionproof probe and a ZR402G non-explosionproof converter.

Model ZR202S is an integrated type which combines a probe and a converter. Both Zirconia oxygen analyzers do not need a sampling device, and allow direct installation of the probe in the wall of a flue or furnace to measure the concentration of oxygen in the stack gas. The converter displays the cell temperature and cell emf in addition to the oxygen concentration.

This analyzer is most suitable for monitoring combustion and controlling the low-oxygen combustion of various industrial furnaces in such explosive atmospheres as at petroleum refineries, petrochemical plants, and natural gas plants.

ZR202G Integrated Type Zirconia Oxygen Analyzer

2009-12-18T01:55:00.000-08:00

Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control in a wide variety of applications and help industries to save energy. The applications range from energy-consuming industries such as iron and steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, and textiles, to various combustion facilities such as incinerators and small- and medium-sized boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO₂, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution.

The ZR202G Integrated type Zirconia Oxygen Analyzer integrates a probe and a converter, and does not require any sampling system. The probe can be inserted directly into a stack or furnace to measure the oxygen concentration of the stack gas with a temperature up to 700 degree C. The probe uses a highly reliable zirconia sensor and a field-replaceable heater assembly. The analyzer features infrared switches, allowing the user to operate the instrument without opening the cover in the field. An automatic calibration unit is available for fully automated calibration.

The ZR202G is ideal for monitoring the oxygen concentration or achieving low oxygen combustion in large- or small-sized boilers, various industrial furnaces, and combustion equipment.

ZR22G, ZR402G Separate Type Zirconia Oxygen Analyzer

2009-12-18T01:54:00.000-08:00

Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control in a wide variety of applications and help industries to make considerable achievements in energy saving. The applications range from energy-consuming industries, such as iron and steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, and textiles, to various combustion facilities, such as incinerators and small- and medium sized boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO2, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution.

The ZR402G converter is equipped with an LCD touch screen which has various setting displays, a calibration display, oxygen concentration trend display, with easier operation and improvement of display functions. The converter is equipped with various standard functions such as measurement and calculation as well as maintenance functions including self-test. The ZR22G separate-type detector uses a high-reliability zirconia sensor, and its heater assembly can be replaced on site. The detector is mounted, for example, on the wall of a flue and can measure the gases directly.

Tunable Diode Laser Analyzers

2009-12-18T01:53:00.000-08:00

The TDLS200 TruePeak Tunable Diode Laser (TDL) Analyzer is capable of measuring a number of near-infrared absorbing gases in harsh process environments. Able to make measurements under very challenging high temperature and pressure conditions as well as environments containing many corrosive, aggressive, and high particulate content materials, the TruePeak analyzer is one of the most robust process analyzers available.
Analysis in most applications can be conducted in-situ, reducing installation and maintenance costs.
In addition, the TDLS200's ability to perform rapid (6 seconds) and interference free measurements makes it one of the fastest and most accurate process analyzers on the market.
