Dam Monitoring During Construction

Intelligent Geo Data Logger Reads Vibrating Wire Sensors for Dam Monitoring
A hydroelectric dam under construction in Serbia required dam monitoring of several environmental and structural properties to guarantee long-term strength and stability. Therefore the dam’s construction engineers put forth a proposal for a large number of geotechnical sensors to be installed and used during construction. These sensors included vibrating wire piezometers, joint meters, fill extensometers and strain gauges.

Each sensor needed to interface with a universal data logger as part of a long-term logging solution. Additionally, the engineers specified that their desired monitoring solution needed to have a large number of vibrating wire sensor inputs, compatibility with a SCADA system, and the ability for expansion.
