PL/PLM – POWER INDUSTRY
One of the biggest challenges to operators working in the power industry is locating
cables, pipes and markers when operating near high voltage environments, such as
substations and conduits where the presence of large signals overpower most locators.
The PL range is designed for use in areas where excessive magnetic fields, generated
by high voltage equipment and cables, can prevent accurate locating. Dynamic Overload
Protection reduces this effect, allowing uncompromised locator accuracy.
PL models have both Peak and Null modes and also a combined Peak/Null mode which
allows the identification of signal/ground distortion effects by displaying both Peak and
Null response simultaneously.
analyzed to aid ensuring compliance and identify training requirements.
In addition PL locators can indicate depth in Power mode. This is
particularly useful when direct connection of a transmitter to a power
cable may be hazardous or impractical. The Compass feature
aids correct alignment with the target cable, maximizing depth
measurement accuracy.
The 8kHz Fault Find function is a technique that locates a cable sheath fault
using an A-frame attached to the Locator. On-screen arrows help show the fault’s
direction and help the operator locate the fault accurately to within 4" (10cm).
TL/TLM – TELECOM INDUSTRY
Large bundled pairs of cables require specialized location equipment to find a selected signal.
As the Telecommunication utilities continue to deploy highly insulated copper or fiber
cables, tracing bundled cables becomes harder. The TL range features additional high
locate frequencies capable of pinpointing high impedance cables to help address this
problem. The TLM models allow users to locate telecom utility markers, and the internal
data logging system allows for usage to be analyzed to aid ensuring compliance and
identify training requirements.
Most domestic telecom cables have no earth but are sheathed; using high frequencies
allows tracing without needing to ground connections. Once the correct pipe or cable is
located, the operator can accurately locate any cable sheath faults to within 4" (10cm)
meter using 8kHz Fault Find mode with a Radiodetection A-Frame.
TL models have both Peak and Null modes and also a combined Peak/Null mode which
allows the identification of signal/ground distortion effects by displaying both Peak and
Null response simultaneously.
Featuring Compass and Dynamic Overload Protection as standard the TL range aids
cable, pipe and marker (TLM only) location even in electrically noisy environments, while
the addition of three sonde frequencies adds more capability and flexibility.
MULTIPLE POWER OPTIONS
RD7000+ locators can be powered
by Li-Ion rechargeable packs
(standard marker models), NiMH
or alkaline batteries.
DEPTH IN POWER MODE
Allows depth measurements
without using a transmitter.

The PL range identifies the target cable reliably, even in areas of large-scale, trunked
cable deployment of complex electrical networks.
The PLM model adds the ability to locate and estimate the depth of power and other
utility markers. In addition, the internal data logging system allows for usage to be
