OPTICAL SCIENTIFIC INC (OSI) LOA-105 Long-Baseline Optical Anemometer/Turbulence Sensors for Aluminum Smelters

thomson-admin — Tue, 10 Jun 2025 03:14:54 +0000

LOA-105 Optical Anemometer for Aluminum Plants is specially designed for superior performance in tough pot room environments. The sensor uses proven optical technology to measure the airflow velocity through the roof vents. The eye-safe LED transmitter and twin photodiode receiver are placed at either end of the pot room and simply need to “look” through the HF flow to measure the airflow. Its maximum path length of 3 km allows the LOA to handle the biggest of pot room’s easily. The instrument is ready with features such as HF resistant windows and air knives to keep the windows clear. LOA has automatic gain control and continuous self-checking.

The optical technology of the LOA has multiple advantages:

Complete Path-Averaged Measurement – The LOA takes the average velocity rate over the entire optical path. This results in a more representative measurement of the flow – much better than point- source sensors.
Predictable Performance Designed for long-term use in a pot room, all critical components of the LOA are enclosed in air-purged housings and HF resistant windows are used to transmit the IR light into the pot room environment.
Low Maintenance As simple as periodic cleaning and checking alignment.

The LOA-105 has received the seal of approval from the US government with EPA Method 14 Equivalency Approval (the rule for measuring airflow velocity in aluminum roof vents. LOA-105 has captured nearly 70% of the US market. Major players in the industry such as ALCOA, Reynolds and Kaiser use LOA as well as ALCAN in Canada, Comalco in Australia, and ALCOA Europe.

LOA design, based on decades of experience in harsh environments, results in a rugged, extremely reliable sensor, immune from typical error modes. LOA uses AGC circuitry to eliminate the effects of output power drop, contaminated optics, or dusty air. Internal diagnostics alert the user if signal strength gets too low for normal operation. Preventative maintenance, suggested every 6 months, is as simple as cleaning the windows and verifying optical aim. With DSP based design, no field calibration is ever needed.

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.

GasEye Cross Duct MG (Multi Gas)

thomson-admin — Tue, 18 Jun 2024 03:12:15 +0000

GasEye Cross Duct MG (Multi Gas) is a high performance in-situ analyzer that provides analysis for 17 standard gas combinations and can be customised for specific combinations. GasEye Cross Duct MG utilizes tunable diode laser (TDL) absorption spectroscopy. The central unit sends a laser light through the process which is detected by the receiver unit mounted on the opposite side of the process. When a gas of interest is present in this process, it will absorb the laser light. The optical power detected in the receiver unit will depend on the concentration of the gas, temperature, pressure, and optical pathlength according to Lambert’s Beer law. Thus in order to determine the gas concentration, the analyzer requires information regarding temperature, pressure, and optical pathlength. Temperature and pressure signals can be provided by analog inputs, via industrial communication protocols, or as manual values via Webserver or HMI.

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.

Applications

Combustion control (boilers)
Safety monitoring
Electrofilter Protection.

Operating principle

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).

GasEye Cross Duct SG (Single Gas)

thomson-admin — Tue, 11 Jun 2024 01:52:29 +0000

GasEye Cross Duct SG (Single Gauge) is a high performance in-situ analyzer that provides analysis for 23 analytes as standard and can be customised for specific combinations. GasEye Cross Duct SG utilizes tunable diode laser (TDL) absorption spectroscopy. The central unit sends a laser light through the process which is detected by the receiver unit mounted on the opposite side of the process. When a gas of interest is present in this process, it will absorb the laser light. The optical power detected in the receiver unit will depend on the concentration of the gas, temperature, pressure, and optical pathlength according to Lambert’s Beer law. Thus in order to determine the gas concentration, the analyzer requires information regarding temperature, pressure, and optical pathlength. Temperature and pressure signals can be provided by analog inputs, via industrial communication protocols, or as manual values via Webserver or HMI.

SG (Single Gauge)
The GasEye Cross Duct SG (Single Gauge) analyzer consists of a pair of cross-duct sensors – a central unit with a transmitter and a receiver unit. The central 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 receiver unit is connected to the central unit by means of a hybrid loop cable. The GasEye Cross Duct utilizes an internal in-line reference gas cell or a process gas (e.g. H2O) for real-time verification of the calibration status.
