Application Cases

Successful Application of SST400 Inclinometer in Monitoring Bridge Foundation

Bridge is a kind of building that crosses the mountain stream, bad geology or meets other traffic needs to make the traffic more convenient. Bridges are generally composed of span structures, abutments, piers, superstructures and foundations. The function of bridge foundations is to bear all the loads transmitted from the superstructures and transmit them to the ground together with the loads from the substructures.

Why Engineers Use Inclinometer to Measure the Safety of Bridge Foundation?

Because the bridge foundation has been affected by stress, natural environmental factors and strain problems for a long time, the bridges may be dangerous in safety. In order to avoid the occurrence of major accidents due to the health of the bridge foundation, it is necessary to establish a standardized and perfect monitoring system. Among the numerous physical quantities to be measured in the bridge, it is an indispensable task to use the inclination sensor to measure small changes in the inclination angle of the bridge foundation.

Successful Application of Vigor SST400 in Safety Monitoring of Bridge Foundation

The following image shows the SST400 tilt sensor (measuring inclination range: ±5°) is used on site in Sweden for tilt monitoring of bridge foundation. The SST400 precision digital inclinometer outputs a dual-axis 0-5V analog voltage signal to communicate with the data acquisition instrument. The data acquisition instrument wirelessly transmits the collected data to the terminal through the TP-LINK (TL-ANT2409A) directional antenna. The whole system, powered by solar cells, is simple, efficient, convenient and practical.
