The positive pole of battery of laser pointer will be shown.
Straight pipe length after the measuring point at least 0.5 times the pipe diameter; conditions permit to avoid installation in the strong electromagnetic interference, strong radiation, and highly corrosive environments. LGA-4000 laser gas analyzer measurements on the distance of the laser beam propagation, the average concentration of 1.2 If you can not find a straight pipe to meet the above requirements, this requirement can be relaxed . In addition, in order to facilitate the installation and maintenance easier installation and maintenance of the installation location, if necessary, must set up the installation and maintenance platform. Welding the welding of the flange. LGA-4000 laser gas analysis instrument for transmitting and receiving unit are installed in the tested pipe (flue) two welded flanges. After the customer presses the button of laser pointer .
Transmitter and receiver modules are designed light-way adjustment of the body, allowing the two flange concentricity deviation, but shall comply with Figure 3.2 shows the requirements, namely to ensure that the angle between the two flange axis line is not greater than 4o errors. Two welding flanges should generally be welded to the diameter of the measured pipe (flue) on the relative horizontal position. Two welding flange concentricity error allowed diagram. Installation, adjust the transmitter and receiver unit. After welding is completed the welding flange, you can begin installation and adjustment of the LGA-4000 laser gas analyzer emission unit and receiver unit. This section describes the work include: installation of the instrument flange, install the transmitter and receiver, and adjust the instrument flange coaxial. laser pointer can be used by the customer as the practical use.
Transmitting and receiving unit has a standard optical window can withstand a pressure of 5 kg.
