Abstract
(EN)

A system for monitoring the stresses in a pipeline for conducting fluid materials, comprising sets of stress-sensing elements electrically connected together at spaced locations along the pipeline, groups of the sets being electrically connected together to form zones, the respective zones being electrically connected to accumulation centers where data from the sets of sensors is accumulated and reduced, and a central control center electrically connected to the accumulation centers for receiving, interpreting and displaying information from the sensing elements.
