Laser Gas Detection OEM Solutions

Laser Gas Detection · OEM Solutions Overview Although most gases are invisible to the human eye, we are constantly surrounded by them. M easurement technology allows us to determine, q uantify and monitor gases. Be it for our safety or for p rocess optimization; gas measurement technology adds value. Axetris Laser Gas Detection modules (LGD) provide solutions to many challenges in gas analysis. LGD modules are stand-alone, ready-to-use OEM subsystems for the selective detection and monitoring of gases. The sensors used in Axetris LGDs are based on so-called Tunable Diode Laser Spectroscopy...

Laser Gas Detection · OEM Solutions Product Overview The LGD F200 series is perfectly suited for the harsh process conditions in industrial environments. The heated gas cell allows hot and humid process gases to be extracted and measured without causing condensation on the optics. Platform-specific benefits: Hot-wet gas measurement up to 220° C Sub-ppm gas detection in a humid gas matrix High selectivity to target gas and H2O Dual gas measurement with fast T90 Long-term stability due to robust design The LGD Compact series was developed specifically for the needs of extractive and mobile...

Laser Gas Detection · OEM Solutions Fields of Application Environmental Changing conditions are inherent in environmental measurement technology: Variable temperatures, humidity and dust particles are only a few challenges gas measurement faces. Optical measurement technology that delivers stable performance under changing conditions provides a critical advantage. Not only master Axetris LGD modules this challenge with ease, they are also highly selective, and therefore avoid cross- influence from other gases, while doing so. Industrial applications are usually ccompanied by demanding...

Laser Gas Detection · OEM Solutions TDLS Technology TDLS stands for Tunable Diode Laser Spectroscopy. This infrared spectroscopy technique makes use of the binding vibrational and rotational states of gas molecules. These are prompted by the absorption of photons. The absorption results in many organic and inorganic compounds exhibition absorption bands in the near and mid-infrared (IR) spectrum. The strongest absorption bands are usually found mid-IR. In near-IR we find so-called overtones. These are often strongly mitigated absorption bands of those in mid-IR. TDLS uses narrow-band...

Laser Gas Detection · OEM Solutions TDLS Advantages TDLS is the most widely used laser-based gas measurement technology on the market today. Although the basic principle has been known for decades, it is constantly developed further. High selectivity Probably the greatest advantage in laser-based spectroscopy is selectivity. The use of narrow-band diode lasers allows the direct scanning of individual gas absorption lines. Interference through other gases can be avoided – as shown in diagram on the left below. This is an advantage over broadband light-sources as used in NDIR (non- dispersive...

Laser Gas Detection · OEM Solutions Axetris LGD Benefits Temperature stability The maxima of the gas absorption lines change with temperature. This can lead to deviating measured values during temperature fluctuations. To minimize this effect, the LGD modules are equipped with a heated gas cell (LGD F200) or a temperature sensor (LGD Compact). With this, the temperature of the gas cell is kept constant or measured and consequently compensated. As a result, the measured values remain stable and reliable even if the ambient temperature changes. Fast response time Axetris LGD modules feature...

Laser Gas Detection · OEM Solutions Self-contained, easy to integrate Axetris LGD modules come (depending on the configuration) already equipped with communication electronics. Both digital and analog signals sent by the LGD module can be received via a standard RS232 interface. All application-specific parameters can be changed directly through the interface or using the free LGD Frontend software. The compact design of the LGD modules ensures easy integration for almost any application. Based on our many years of experience, we are also happy to advise on suitable equipment, such as...

Laser Gas Detection · OEM Solutions LGD Frontend Software Axetris offers open-source frontend software for all LGD products on www.axetris.com. The .exe file can conveniently be run on any device without the need to install a program. Neither does it require an internet connection. Perfectly suited to be used in the field. The LGD-Frontend start page shows the current measurement of the target gas as well as their temporal course. Parameters, such as integration time or span and offset values can easily be changed in settings. The menu item “Diagnostic Data” also provides the user with...
