Determine the specific installation location of the pressure sensor
In order to determine the number and specific installation location of the pressure sensor, it is necessary to consider each inflation section of the inflation net.
(1) The pressure sensor must be installed along the cable, preferably at the cable joint.
(2) Each cable should be equipped with no less than 4 pressure sensors, and the two pressure sensors near the telephone office should be no more than 200m apart.
(3) Install one at the beginning and one at the end of each cable.
(4) Each cable should have one branch point installed. If the two branch points are close (less than 100 meters), only one can be installed.
(5) One cable should be installed at the location where the cable laying method (overhead or underground) changes
(6) For cables without branches, due to the consistent cable program of the base wire, the installation spacing of pressure sensors should not be greater than 500m, and the total number should not be less than 4.
(7) In order to facilitate the determination of the fault point of the pressure sensor, in addition to installing the pressure sensor at the starting point, an additional one should be installed at a distance of 150-200m from the starting point. Of course, in the design, economic and technical factors must be considered. In places where the pressure sensor does not need to be installed, it should not be necessary to install it.
