Radiodetection
The geophysical technique called radiodetection is an electromagnetic method that allows to accurately locate pipes and buried cables.
Basically, its operation consists in detecting the magnetic field resulting from the flow of an electric current. Within our geophysical services , the basic possibilities of operation will be:
- The detection of active cables by which some type of current flows
- Or when the cables or pipes are not active, induce a signal at an accessible point in the pipeline or cable to be detected and locate that signal in the study area in order to locate its position
The location will be both surface and depth.
The radiodetection equipment is therefore composed of a receiver and an emitter. The receiver detects the magnetic field resulting from the flow of an electric current induced in a line. This field is called a signal. The transmitter emits a signal by connection, induction or by certain accessories.
Both the transmitter and receiver have different modes of operation (Power signal, Radio signal, 8 kHz signal, 33 kHz signal, passive scan, active scan, tracking, peak response, zero response, etc.) and certain accessories Allow the introduction of an "emitter" into pipes / manifolds, etc. Which will be followed by the surface receiver.
Radiodetection applications
Fundamentally the detection and location of buried cables and pipes, whether active or passive. Location and monitoring of collectors, pipes, abandoned galleries visitable and / or accessible, etc. It is very useful when detecting urban services before tasting, sounding, etc.
