Split-box Pipe and Cable Locator

DESCRIPTION

The Split-box Pipe and Cable Locator is a hand-held

instrument in the classic “split-box” design, consisting

of a transmitter and a receiver. The instrument traces

underground conductive networks such as water and gas

mains, telephone, cable TV , and electric power cables. It

determines buried lines depth and locates underground

metallic masses such as valve caps and manhole covers.

Designed with patented super-inductive technology, the

Split-box Pipe and Cable Locator is lightweight, portable,

and easy to use. For easy transport, the instrument and

accessories are supplied with a protective tote bag.

APPLICATIONS

To locate and trace an underground metallic line, the line

is energized with a radio-frequency signal generated by the

transmitter and then detected by the receiver. Inductive

or conductive modes of operation are available.

The inductive operational mode does not require direct

mechanical line connection. The transmitter can energize a

buried line without the need to uncover it. Just place the

transmitter on the ground or pavement above the line

which, once induced with the transmitted signal,

retransmits the signal through the ground and air in a

pattern that corresponds to its path. The line carries the

signal several hundred yards depending on its depth, the

mineralization and conductivity of the soil, and the

transmitter power setting.

The conductive mode of operation requires the line to be

exposed so that a direct connection can be made.

Conductive energizing is preferred over inductive

energizing because it results in more highly defined signal

coupling. The signal generated does not spread to other

conductive lines in the vicinity of the traced line. Using a

ground rod with the direct connection increases the

energizing efficiency and, therefore, the length of line that

can be traced.

Two methods of receiving the transmitted signal are peak

detection and null detection. The method used depends

on the placement of the receiver. When held at a right

angle to the surface of the ground and moved back and

forth across the line to be traced, the receiver detects

peaks (maximum signals) when directly above the line.

When the receiver is held so its face is parallel to the

surface of the ground and moved back and forth across

the line, the detection of minimum signal or null (absence

of signal) indicates that the line is directly below.
