  • Page 10: General User Information

    GENERAL USER INFORMATION 1.1 LGD F200P2 introduction Axetris’ laser gas detector (LGD), “LGD F200P2,” is a system for the continuous monitoring of gases such as NH and (H O), HCl and (H O), CH or CO . Based on state-of-the-art Tunable Diode Laser Spectrometry (TDLS), the system has a very high selectivity to the target gas and features an innovative, patented measurement principle without the need for a physical reference channel.

    Dust or condensing water in the measurement cell leads to signal reduction of the sensor. It is therefore crucial to ensure that the measurement gas flow is free of dust and that condensation cannot occur: Axetris AG LGD F200P2 Operating Instructions - Rev D 19.09.2018 12/60...
  • Page 13: System Layout And Materials

    Prevent any dust, insulation or other material from entering the measurement cell. The main external features of the LGD F200P2 are the housing, the electronics housing, and the gas-in and gas-out connectors. On the inside, the system is equipped with an electro-optic module containing a laser and photo-diode, a measurement cell, and a high reflectivity mirror.

    First, plug the DB15 connector into the instrument prior to connecting the RS232 and the power supply. Plugging the AC/DC adapter into a 100–240 VAC source turns on the LGD F200P2 (in case another power supply and RS232 cable are used, please keep in mind that it is important that the RS232 cable is a straight one and not the cross-over version.

    (optional) The LGD F200P2 housing is dust-tight but not gas tight. For thermal decoupling reasons, an air space exists between the electro-optic elements and the measurement cell. Under very unfavorable conditions the gas present in this space might contribute to the measurement signal.

    Additionally, the interface logs system status information to the computer (“.LGD” file extension). Sending this file to the Axetris support team helps to analyze the behavior of the sensor. The software automatically generates the following path where the log data is stored: “C:\ProgramData\Axetris LGD\Interface_Logg_Files”.
