GasEye Extractive
The GasEye Extractive is a versatile gas analyzing tool for industrial process applications. A process gas sample is continuously fed into the analyzer where it is analyzed in real-time utilizing laser absorption spectroscopy.
It can be configured to operate in the near-infrared (NIR), mid-infrared (MIR), and infrared (IR) wavelength range thereby allowing to analyze the majority of gases of interest in the industrial process monitoring.
GasEye Extractive analyzer is assembled in a 19” RACK IP20 or wall-mounted IP66 enclosure.

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.
Extractive Versions
GasEye Extractive 19″ RACK analyzer is assembled in a standard 19-inch rack 4U version.
It exists in several various configurations from single gas to multi gas applications.

The GasEye Extractive Wall Mounted type analyzer exists in general purpose and hazardous area configuration (version Ex1). It exists in several various configurations from single-gas to multi-gas applications. The system is IP66 rated with ambient temperature ranges from -30ºC to +60ºC and can be mounted outside without a need for a container.
GasEye Extractive Ex1 provides Ex p (purge and pressurization) type of explosion protection. Ex p pressurized equipment is the technique of guarding against the ingress of the external atmosphere into an enclosure by maintaining a protective gas therein at a pressure above that of the external atmosphere. The overpressure is maintained either with or without a continuous flow of the protective gas.
