How is the pressure sensor installed?1. Correct installation method of pressure sensor:(1) Verify the frequency response value of the pressure sensor under normal atmospheric pressure and standard temperature conditions through appropriate instruments.(2) Verify the correctness of the code of the pressure sensor and the corresponding frequency response signal.2. Determine the specific installation locationIn order to determine the number and specific installation location of the pressure sensor, it is necessary to consider each inflatable section of the inflatable net.(1) The pressure sensor must be installed along the cable, preferably at the cable joint.(2) Each cable is equipped with no less than 4 pressure sensors, and the two pressure sensors close to the telephone office should not be too far apart by 200m.(3) Install one at the beginning and end of each cable.(4) One branch point of each cable should be installed. If the two branch points are close (less than 100m), only one can be installed.(5) One cable should be installed at the place where the cable laying method (overhead, underground) changes.(6) For cables without branches, the installation distance of pressure sensors should not be 500m, and the total number should be no less than 4.(7) In order to facilitate the determination of the failure point of the pressure sensor, in addition to installing the pressure sensor at the starting point, an additional one must be installed at a distance of 150~200m from the starting point. Of course, economic and technical factors must be considered in the design. Where the pressure sensor is located, it should not be installed.
