Definition - What does Flux-Sensor Device mean?
A flux sensor device is a non-destructive method of pipeline testing to detect the change in flow of magnetic field. In trenchless rehabilitation, inspection techniques such as this are used to detect corrosion or damage due to corrosion, such as pitting, in steel pipelines. Trenchless inspection methods help save cost and time by pinpointing problem areas that can then be targeted for repair.
Cured-in-place pipe (CIPP), sliplining and pipe bursting are some of the methods that can be used to repair pipes damaged by corrosion.
Trenchlesspedia explains Flux-Sensor Device
Flux sensor uses a powerful magnet in order to magnetize the steel pipeline under inspection. A magnetic circuit is created along the pipe wall by the magnets and the sensors are located between them. Corroded areas and areas that have been eaten away due to corrosion will allow the magnetic field generated from the magnet to leak.
The sensors pick up this disruption in the magnetic field. The results are studied in order to detect damaged areas and to estimate metal loss in the pipeline.
