MIT Cable Detector
It is essential to locate cables and metal pipes to check the ground for the presence of cables and metal pipes
before groundworks and digging.
The advantages at a glance:
Detection and localization of buried cables and metal pipes
Inspection of the subsoil to ensure safe excavations
Estimation of the depth of located cable
Both passive and active localization of cables and pipes
Suppression of radio interference
Low weight as well and easy handling
Attractive price-performance ratio
Principle of Operation
Long cables and metal pipes act like a receiving antenna that are able to pick up electromagnetic fields (e.g. from long-wave transmitters). This leads to magnetic field noise generation around the cables.
The MIT-Cable Detector receives the magnetic noise and converts it into audible signals.
To perform a search, the device must be moved over the search area.
A sound signal indicates the localization of a cable.
Additionally, its depth can be determined by tilting the device. The supplementary transmitter also allows cables to be traced that emit only a weak signal.
Cables can be detected up to 2 mtrs. depth depending on the strength of the signal and/or if an additional transmitter will be used.
Construction
Antenna Reception of electromagnetic noise signals of cables and metal pipes
Operating unit Transformation of electromagnetic noises into accoustic signals
Headphones Output of acoustic signals for locating cables and metal pipes
Additional Transmitter
The additional transmitter is used for active localization of cables or metal pipes that emit only a weak signal. It induces
a magnetic current within the cable/pipe to then locate or follow.
