Introduction
The Process Gas Analysis System of LGA-4000 series (In-Situ model), based on the technology of the diode laser absorption spectroscopy (DLAS), is the gas laser analysis system with integrated design and high integration. The system, by in-situ measurement that needs no sampling pretreatment, is able to
rapidly, accurately and reliably measure various industrial process gases and flue gases emitted for environmental protection, to provide the best solution for the on-line gas monitoring in various industries.
Features
1. Laser In-Situ measurement, rapid response, high measurement precision;
2. Integrated positive pressure explosion-proof design, safe and reliable;
3.Modular design, with the possibility to renew all functional modules on site, easy to
maintain;
4. High intelligent interface, easy to operate.
The transmitting unit of the Process Gas Laser Analysis System of LGA-4000 series (In-Situ model),
consisting of the man-machine interface, the laser drive module, the central processing module, the
diode laser and other modules, mainly realizes diode laser driving, spectral data processing, humancomputer interaction
and other functions.
The receiver units, consisting of the photoelectric sensor, the signal processing module, the positive
control module and other modules, mainly realizes signal processing, power control and other
functions.
