Monitoring probe SenSpot™

for constructionflexiblemulti-parameter

SenSpot™ wireless scour meter provides an easy way to install a scalable solution for measuring bridge scour, hydraulic damage, or slope stability. Bridge scour refers to the removal of sediment such as sand, soil, and rocks from around bridge piers or abutments by fast moving flood current. It can cause erosion around the bridge piers or abutments. As scour occurs progressively, supporting material around the bridge foundation is removed and it can lead to settling or other forms of foundation instability. Resensys Scour Probe SenSpot™ measures soil/sediment level close to the bridge foundation with a novel method that is completely different from current available methods. The probe or sensing element consists of up to eight sediment sensing glands that are connected to the electronic transducers through a cable. The nodes are located inside a waterproof mechanically flexible tube. The length of the tube (scour probe) and the spacing between successive sediment sensors can be customized according to the application needs. The probe can be buried to insert into sediment in locations with a high risk of scour. In applications where the probe is inserted into sediment, it can be encapsulated in a stainless-steel C-shaped or U-shaped profile, so it can be easily driven into the required depth using a hammer or similar tool. Also, each node has a temperature sensor with resolution of 1°C (or 1.8°F) that allows further verification of whether the node is inside the soil or water. Typically, the temperature variations are smaller at nodes in the water comparing the nodes inside the soil. Featured Applications • Bridge scour monitoring • Hydraulics monitoring
