Product Datasheet Laser Gas Detection OEM Module LGD F200P2-H NH3 1 General description 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 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 slightly bigger LGD F200 (H) version features optional 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 costof-ownership and make the LGD F200 the ideal instrument for your OEM applications. 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 Low cost-of-ownership 10-30V power supply Digital and analog output Hot-gas measurement up to 190°C Process control: SCR, incineration & combustion processes, … Emission monitoring: Power generation, engine development, waste incineration furnaces, … Environmental monitoring: Product Datasheet Landfill & green-house gases, livestock, ...

To increase vibration and shock protection Axetris provides rubber fixations that can be mounted between the brackets and the instrument mounting location. 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...

11 Caution 12 Important notice / Disclaimer 11.1 Product damage  Read all instructions carefully before using the device.  The LGD F200 laser gas detection modules are calibrated for a particular gas and concentration range. Do not use the senor outside of its specifications  The sensor is not suited for measuring gases with a dust load. The incoming measurement gas must be conditioned in order to avoid dust and condensation of liquid in the sensor. Gas loaded with particles or other substances can eventually contaminate the cell and make it necessary to service the instrument.  The...
