ABSTRACT

The paper presents a study on the measurement stability of a landslide sensor based on four magnetic amorphous wire strain gauges used in an Wheatstone bridge configuration. The sensor is aimed for in-situ monitoring using a distributed sensor network. The experiment has been performed in the lab using a test stand, while a time step progressive deformation has been applied to the sensor. Results show a good stability of the measurement and a variable sensitivity with respect to the bending point.
