Pipe locators are ideal
damage-control tools for those engaged in boring or directional
drilling work.
Basic Pipe locators components include:
-
Hand-held receiver
-
Compact transmitter unit
How they work
Different frequencies and modes are used to find locations of
utility lines by detecting magnetic fields created by electrical
current that passes through them. The receiving unit may be all
that is necessary to locate electrical and television cable
signals. Whatever method is used, the receiver processes
information and displays data on a screen at the top of the
unit.
To find telephone cable and metallic pipe, the transmitter unit
is connected to cable or pipe and current is sent through the
line, creating a signal that is detected by the receiver.
To find PVC pipe with a tracer wire, the wire is energized by
the transmitter to provide a signal that is read by the
receiver.
Utility crews often use locators to:
Pipe locators also are valuable
tools for screening grounds before driving tent stakes!
