In the GasEye Cross Duct analyzer, the laser wavelength is specifically chosen to match the fingerprint region of the particular gas of interest and is being continuously scanned over the absorption line(s). Since full spectral information is recovered with very high spectral resolution the analyzer remains immune to foreign gas broadening and is immune to cross-interferences from dust and any other gas constituents in the process. GasEye Cross Duct by design can operate in several wavelength regions from Near-Infrared to Mid-Infrared.

Operating principle

GasEye Extractive is a laser spectrometer that uses single line molecular absorption spectroscopy. A semiconductor laser emits a beam of infrared light which passes through the process and impinges the detector on the receiver side. When the target gas is present the light intensity changes and this can be used to determine the concentration of the measured specimen. The wavelength of the radiation emitted by the laser is chosen to match the specific absorption line wavelength of the gas. The laser continuously scans this single absorption line with a very high spectral resolution. The measurement is free of cross-interferences since the laser light is absorbed very selectively by only one specific line in the scanned spectral range.

INFLUENCES ON THE MEASUREMENT

Temperature

The influence of temperature on the measured absorption line is compensated by internal algorithms. The process gas temperature must be provided as a signal into the instrument. The temperature measurement is used to apply a correction of the temperature on the observed line strength. Temperature compensation is obligatory and without it the concentration output is erroneous.

Pressure

The influence of pressure on the measured absorption line is compensated by internal algorithms. The process gas pressure must be provided as a signal into the instrument. For known pressure values, the GasEye Cross Duct spectrometer adapts the line shape. Additionally, an external pressure signal can be fed to the analyzer to provide complete mathematical compensation of the pressure influence including the density effect (depending on a specific application and target gas).

Interferences

The GasEye Cross Duct can measure the desired gas components very selectively. It may happen that the absorption line of the measured gas is influenced by the presence of other gases. This influence is compensated by the full shape of the detected signal curve analysis and applying algorithms that correct the discrepancies accordingly.

MG (Multi Gauge)
The GasEye Cross Duct MG (Multi Gauge) analyzer consists of a pair of cross-duct sensors – a transmitter and a receiver unit as well as a central unit. The transmitter unit emits laser radiation directly through the process containing the constituents of interest. The receiver unit collects the radiation on the other side of the process duct. The central unit, located close to the transmitter unit (< 2 meters) contains analyzer electronics, MMI and I/O. The receiver unit is connected to the central unit by means of a hybrid loop cable (included) and the transmitter unit is connected to the central unit by one or two electrical cables (included).

]]> The Series 2000 represents a complete line of Thermal Conductivity Detector (TCD) based analyzers which can be applied in a wide range of applications and industries. By using field proven filament-based and semiconductor based TC detectors, Teledyne is able to continuously monitor hydrogen and a variety of other gases of interest in either binary or multi-component sample gas streams.

Series 2000 Platform

To contend with the numerous and varied analyzer requirements among industrial users, Teledyne has developed a feature rich, user-friendly platform. The Series 2000 comes with a standard software program incorporating such flexible features as (3) user-programmable ranges, automatic calibration, and customer selectable gas constituents.

Thermal conductivity is a basic property of gases that relates to their ability to conduct heat. Good conductors of heat such as H2 and He, have a high thermal conductivity whereas poor conductors of heat, such as CO2 and Ar, have low values. This ability to conduct heat forms the basis of detecti​on. The Series 2000 analyzes gas compositions by continuously comparing the sample gas with a reference gas (sealed or flowing) of known thermal conductivity. This comparison is performed in a 2 chamber detector cell block. Reference gas occupies one chamber and sample gas the other.​

A pair of temperature-sensitive heated filaments is mounted in each chamber. These filaments are part of a Wheatstone Bridge circuit. Should the sample gas composition change, its thermal conductivity will also change, conducting different amounts of heat away from the sample gas filaments. Since the resistance of the filaments is a function of their temperature, the resistance changes when the sample gas changes.

Any such change results in an imbalance in the Wheatstone Bridge, resulting in an electrical signal proportional to the change. Since the temperature of the filaments is tightly temperature controlled, the Series 2000 provides an accurate measure of any change in the sample gas composition. Teledyne offers this cell design in a variety of wetted parts to contend with corrosive gas streams typically found within the hydrocarbon processing industry.

Sensor Operating Principle

The thermal conductivity sensor measures the concentration of a specific gas between a hot surface resistor and an ambient temperature reference resistor using the thermal conductivity coefficient of the gas itself.

Sensor Description

The sensor structure consists of an integrated heater located on a thin electrical and thermal insulating membrane. Two thin film resistors are used for heating and measuring the temperature of the membrane. Two resistors are integrated on the silicon beside the membrane for the compensation of the ambient temperature changes.

Gases which have a lower density than air (CH4) cause a decrease on the surface membrane temperature. On the other hand, gases with densities heavier than air (CO2) increase the temperature of the measuring resistor.

Options

​C – Integrally mounted auto-calibration valving

H – Stainless steel cell block with gold filaments (for gas streams with H2S)

K – 19″ rack mount for 2000A

L – Gas selector panel for sample and cal gas selection and flow control

N – 220 VAC operation

R – Sealed reference (for filament-based TCD)

]]> COMTEC^® 6000 DustEx provides permanent and reliable gas analysis in Ex zones 21/22 with high dust loads. The DustEx probe is robust and designed to withstand the abrasive forces of high dust atmospheres.

Information

The COMTEC^® 6000 DustEx is the standard InSitu analyzer system for use in dust explosion zones 21/22

In accordance to the tough demands placed on measuring systems in high dust processes, the DustEx is ATEX*certified to II 2D Ex tD A21 IP6X T133°C/T141°C.

Being able to precisely determine the proportion of oxygen and CO_e in flue gas is the starting point for the safe and optimized operation of incinerators, as oxygen and CO_e are dependent to one another within a combustion process. Undesirable developments can thus be identified and rectified earlier, before any damage is caused.

The COMTEC^® 6000 DustEx is also available for O₂ only measurements.

Applications

• Energy optimization
• Emission measurements
• Power generation
• Waste incineration
• Combustion control.

Features

• InSitu measurement in real-time
• Overview of calibration history
• ATEX certified for zones 21/22
• Low-maintenance
• Self-monitoring
• Sensor life expectancy on display
• Gas tight sensor construction.

*Please note ATEX certification is only recognised in Europe. Australia recognises IECEx. For IECEx, a third (certification) party is is required to make the design and manufacturing assessment to issues the IECEx certificate. In practice this means IECEx 02 requires more evidence and assurance from the manufacturer during the quality certification process. ATEX and IECEx both use the same standards (eg EN-IEC 60079-0), so they are technically almost identical.
