Company of the Leister Group INFRARED SOURCES MASS FLOW DEVICES LASER GAS DETECTORS MICRO-OPTICS Product Datasheet Laser Gas Detection OEM Modules LGD F200-A NH3 Axetris is offering Laser Gas Detection (LGD) modules with exceptional advantages and value for the customer. Tunable Diode Laser Spectrometry (TDLS), enhanced by proprietary technology, is used for the measurement of designed for integration by Original Equipment Manufacturers (OEMs), active in the field of gas detection and monitoring in diverse The LGD F200 series is based on a contact- less, near-infrared absorption measurement of the target gas. The systems are self-contained, ready-to-use OEM modules, using a flow- through cell set-up for extractive features cell heating up to ~\90°C for hot gas measurements in process control and environmental compliance related applications. The system has micro-processor-driven read- out electronics and digital and/or analog data outputs for industry-standard connectivity. Proprietary electronic lock-in technology allows separating gas absorption information from electro-optical system information, eliminating the need for a physical reference channel and providing continuous sensor status monitoring. Low maintenance operation and long life time provide customers with exceptionally low cost- ideal instrument for your OEM applications. Main applications • Process control: SCR, incineration & combustion processes • Emission monitoring: Power generation, engine development, waste incineration furnaces, ... • Environmental monitoring: Landfill & green-house gases, livestock,... • Made for easy integration by OEMs • Optical, contact-less measurement • Accurate laser-diode electro-optics • High selectivity • Fast response • Continuous sensor status monitoring • Digital and analog output • Chemical engineering: Production control & monitoring ...

5 Mechanical interface The module is equipped at its front & back end with mounting brackets. The brackets can be fixed in four different 90° rotated positions. To increase vibration and shock protection Axetris provides rubber fixations that can be mounted between the brackets and the instrument mounting location. 6 Gas Conditioning and filtering Due to the multitude of applications for the LGD, gas conditioning and filtering has to be carried out by the integrating Original Equipment Manufacturer (OEM). The following points are crucial in order to operate the unit correctly and to achieve...

8 Factory calibration The LGD F200 are factory calibrated to customer specifications. In some cases a more specific customer calibration might be needed where complicated measurement conditions or complex gas matrices are present. In this case the customer might proceed to perform his own calibration of the system. Systematic differences between the factory calibration set-up and the customer measurement/calibration set-up can be handled with an off-set and gain adjustment of the sensor. 9 Installation instructions Questions related to the user interface, startup, installation and use of...
