Select the installation type
1) Wall-mounted type: This type of installation is usually selected for normal indoor inspection.
According to the size of the outer hole of the mounting bracket (optional), fix two or four 6mm expansion
bolts on the wall, and fix the bracket and the detector with screws, nuts, spring washers and flat washers.
Then use 6x30mm nuts and spring washers to fix the expansion bolts on the wall, see the picture
below.
Note:
The installation location must be well grounded or insulated. Leakage of electricity may cause the
detector to work abnormally.
2)
Pipe-mounted type: The installation thread size of the instrument is M45*P2.0. During the
installation process, hold the detector with both hands so that the sensor is parallel to the installation
thread, align the screw mouth, rotate the detector clockwise, and then install the detector on the target
position. In order to prevent air leakage at the threaded interface, suitable raw tape can be wrapped
around the threads on the sensor head before installation.
Note:
The pipe-mounted type requires that the inside of the pipeline is normal temperature and
pressure (temperature -20~50
℃
, pressure 0.1mPa) and humidity ≤95%RH. If the above conditions are
not met and this installation method is required, please contact the manufacturer for a solution.
