Pressure sensor installation method and troubleshooting method

Pressure sensor installation method and troubleshooting method

The pressure sensor is a commonly used sensor and its application range is very extensive. Users use the pressure sensor for its installation and fault handling is the most concern, which relates to the pressure sensor can not be used normally, the following Xiaobian to introduce the pressure sensor installation method and troubleshooting methods.

Pressure sensor correct installation method:

(1) Verify the frequency response of the pressure sensor under normal atmospheric pressure and standard temperature conditions with appropriate instruments. (2) Verify the correctness of the pressure sensor code and the corresponding frequency response signal.

Determine the specific installation location In order to determine the number and the specific installation location of the pressure sensor, it is necessary to consider each inflation section of the inflator.

(1) The pressure sensor must be installed along the cable, preferably at the cable gland.

(2) There shall be no less than 4 pressure sensors installed on each cable, close to the two pressure sensors of the telephone exchange and shall not be separated by 200m.

(3) Install one at the beginning and at the end of each cable.

(4) One branch point should be installed for each cable. If two branch points are close to each Other (less than 100 m), only one can be installed.

(5) One cable change method (heading, underground) should be installed

(6) For unbranched cables, because the cable patterns of the barriers are the same, the installation distance of the pressure sensor is not 500 m and the total number is not less than 4.

(7) In order to facilitate the determination of the pressure sensor failure point, in addition to the installation of the pressure sensor at the starting point, 150 ~ 200m away from the starting point, but also to install an additional one of course in the design, we must consider the economic and technical factors, do not need to install Where pressure sensors are located, they should not be installed.

Pressure sensor failure solution:

(1) Electronic means measure the absolute air pressure, making the control of the inflated state of the line more complete and continuous.

(2) From both dynamic and static aspects, the leak point can be estimated in advance.

(3) Determine the change in the pressure of the cable during the time, so that it is possible to estimate the time of the inflation, that is, when a negative variable occurs, the reduction amount can be determined in advance, so that the final pressure value of the pressure sensor fault segment and the corresponding diffusion are determined. time.

(4) Verify the gas path of the cable. Along with the production of barometric telemetry equipment, pressure sensors are also used on cables. For the normal operation of the entire air pressure telemetry system, the pressure sensors need to be matched with the air pressure telemetry equipment to coordinate the work. From the air pressure telemetry system, there are two types of work methods: “select line and select points” and “select line”. Then there must be a reasonable solution to the pressure sensor failure. Through the above description of the article now we all know the correct installation of pressure sensors and pressure sensor troubleshooting methods, the user understands this knowledge for the future pressure sensor installation of emergency maintenance is a great advantage.
