Tunable Diode Laser Spectrometry (TDLS), enhanced by proprietary technology, is used for the measurement of CO2, NH3, CH4, HCl, (H2O). The modules are designed for integration by Original Equipment Manufacturers (OEMs), active in the field of gas detection and monitoring in diverse industries. The LGD F200 series is based on a contactless, near-infrared absorption measurement of the target gas. The systems are self-contained, ready-to-use OEM modules, using a flowthrough cell set-up for extractive measurements. The LGD F200 (H) version features cell heating up to 190°C for hot gas measurements in process control and environmental compliance related applications. The system has micro-processor-driven readout 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-of-ownership and make the LGD F200 the 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, ... Key features • Made for easy integration by OEMs • Optical, contact-less measurement • Accurate laser-diode electro-optics • High selectivity • Fast response • Self-contained • Continuous sensor status monitoring • Low maintenance • 10-30V power supply • Digital and analog data interfaces • Chemical engineering: Production control & monitoring ... • Safety: Leak detection, refrigeration, toxic gases, . • Climate control & monitoring: Livestock, climate chambers & rooms, ..

_ • ® axetris Company of the Leister Group 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...

Company of the Leister Group 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,...
