Laser-Based Thermometry |
Introduction Through a marketing agreement with MetroLaser, Inc, the developer of the core TDLAS technology of the instrument, Bergmans Mechatronics LLC is offering the LTS-100 sensor to the industrial marketplace in an effort to reduce the costs and improve the performance of traditionally difficult temperature and H2O measurements.

System Overview The implementation of this concept for measurement of conditions within a furnace or boiler is shown at right. A tunable diode laser within the LTS-100 Processing Unit generates a beam of laser light. The beam wavelength is continually modulated, or "tuned", over a narrow portion of infrared region of the electromagnetic spectrum. The beam is transmitted down the length of an optical fiber and enters the Launch Optics Enclosure mounted on one side of a furnace or boiler. The beam then passes through the combustion gasses and strikes a photodiode detector within the Detector Enclosure mounted one the opposite side of the furnace or boiler. The output of the photodiode detector is transmitted to a data acquisition board contained in a PC within the Processing Unit. Software on the PC calculates gas temperature based on calibration data relating beam attenuation and laser wavelength to gas temperature and water concentration. Further details on the theory and performance of the instrument are provided in the technical papers below. |
