Device introductory information
12.1 Purpose of use and physical configuration
The AG-105 is an automatic utility locating transmitter
designed for the generation of the propagating electric
oscillations in the traces of the buried utilities using
electromagnetic method of the trace search.
Field of application:
- Housing maintenance and utilities sector;
- Communications industry;
- Electric power and heat supply industries;
- Gas supply.
The device is shown in the enclosure-case containing:
1 - information panel on the inner side of the cover;
2 - battery holder with the handle in the center for removing;
3 - push-button and LED indication panel.
DISTINCTIVE FEATURES
The extremely high output power and autonomous operating time for such a compact battery
set (“type C”x8) and small size of the device.
The universal power supply provides an opportunity to reach the output power of over
20W
.
In the autonomous power supply mode the “life cycle” depends on the quality of the batteries
applied “type C”.
For example,
under initial output power of
7 W
in the continuous oscillation mode the “life cycle”
is
approximately
equal to
5 hours
and under initial output power of
15 W
in the intermittent
modulation mode the “life cycle” is approximately
25 hours
(with the use of standard “fresh”
batteries, e.g. “Energizer C”). Using high-capacity batteries (for example, “Duracell ULTRA”), the
duration of the autonomous operation can be extended by 20-30%. If “12V” external battery (e.g.
automotive) is connected the operation time is defined by the battery capacity. When connecting
to the external power source of “15V” the operating time is not limited.
The dimensions of the portable device in the casing amount to
216x180x105
mm and
weight
does not exceed
2 kg.
The above-mentioned features are secured by the application of the unique superefficient
modification circuit technology of power amplifiers composition
CLASS D
. Pulse output amplifier
reaches
85%
efficiency
which is particularly important for the energy consuming devices with an
autonomous power supply.
AG-105 is the best-in-class of the “portable utility locating transmitters with low-
powered autonomous power supply” in terms of the qualitative characteristics, namely
“power –operating life– dimensions – weight”.
The device generates a sine-shaped signal continuously “Co” or discontinuously “Pu” for utility
(cables and steel pipelines) locating and special dual-frequency signal “2F” for identification of
“someone else’s” utility or for flaw detection of earth leakage.
Such a unique (among other transmitters) peculiarity as uncommonly high potential output
current (more than
5A
) make it possible to carry out utility locating of not quite adapted to such
procedure the extraordinary low-resistance utilities (e.g. “earthed” pipelines) when the significant
part of the output current inefficiently flows to earth already near the connection point.
