4000KN axial force meter

Application of 4000KN axial force meter:

The vibrating wire type reaction force (axial force) meter is a type of vibrating wire type load sensor with high resolution, strong anti-interference performance, sensitive response to concentrated loads, reliable measurement values, and good stability. It can measure the reaction force of the foundation on the upper structure for a long time, and the load during steel support axial force and static pressure pole test. It is equipped with an installation bracket (purchased separately) for matching, and the installation operation is extremely convenient.

4000KN axial force meterBurial and installation:

Axial force meters are used in various occasions, and the working and construction conditions of the instruments are also different. If necessary, please contact our factory in a timely manner. The following mainly describes the installation situation of supporting axial force measurement:

l、 The installation bracket for the axial force meter provided by our factory is securely welded to the steel plate on the supporting bracket's cow leg (flexible head) on the end face of the circular steel cylinder without grooves. During welding, it must be aligned with the steel support center axis and the installation center point.

2. After cooling down, push the axial force meter into the welded circular steel cylinder of the mounting bracket and firmly fix it in the mounting bracket with the 4 M10 screws on the circular steel cylinder, so that the axial force meter will not slip off during support lifting.

3. Measure the initial frequency of the axial force meter to see if it matches the initial frequency at the factory (≤± 20Hz), and then properly tie the cable of the axial force meter to the inside of the two wings of the mounting bracket, so that the steel support will not damage the cable during the lifting process.

4. After the steel support is lifted in place, that is, the end of the installation frame (the vacant end) is aligned with the steel plate on the enclosure wall. It is best to add another steel plate 250mm × 250mm × 25mm between the axial force meter and the wall steel plate to prevent the axial force meter from sinking into the wall under the force of the steel support, causing inaccurate measurement and other situations.

5. Before applying prestress to the steel support, the cable of the axial force meter should be led until it is convenient for normal measurement, and the initial frequency of the axial force meter should be measured and recorded.

6. After applying pre stress to the steel support to meet the design standards, normal measurement can begin.

7. Determination of variables: In general, the difference between the change in the measured supporting axial force at this time and the initial supporting axial force at the same point is the current change. And fill in the achievement summary table and draw the curve of the variation of the supporting axial force.
