What are thermistor strings? A thermistor, coined from “thermal” and “resistor”, is a sensor that changes resistance based upon temperature. It is used to measure temperatures within a specified range by using calibration tables to convert from resistance to temperature. Thermistor strings are cables with integrated thermistors, usually pressed into a bead-like node ...
The IoT solution is designed to lie dormant until it picks up critical movements. If the sensors pick up critical movements, the IoT system sends a warning. The system uses a technology called vibrating wire where sensors can pick up even minimal changes in the rocks. ...
Calculated temperature trends (in the order of 0.01°C/day) agree well with those obtained from the very accurate vibrating wire temperature sensors. A couple of more measurements have been made since then, where the latest was using Silixa XT-DTS with a sampling resolution of 0.25 m. Evaluation using DamTemp, and based on short-time DTS ...
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. ...
