Global Positioning System Pro XRS |
The
GPS Pathfinder® Pro XRS receiver is an easy-to-use
GIS data collection and data maintenance system
that provides real-time submeter accuracy. The
Pro XRS offers GPS, WAAS, satellite differential,
and beacon capabilities. The integration and flexibility
of these technologies means that you have less
equipment, cables, and batteries to carry.
Feature
and attribute data are input with the TerraSync
software running on Trimble's GIS TSCe
field device or a user-supplied Windows field
computer, Trimble's Asset Surveyor® software
running on the TSC1 data collector, or
your existing data collection software. The
GPS Pathfinder Pro XRS system provides two-way
data flow between the field and GIS, facilitating
the data collection and data maintenance processes,
and ensuring that you always have current data
for decision-making.
Because the GPS Pathfinder Pro XRS integrates
real-time DGPS, it is easy to navigate directly
to an asset for verification and update. By
taking advantage of these real-time features,
you remove the need for postprocessing GPS datafurther
closing the gap between field work and your
GIS.
KEY

Magnetic Locator Model GA-72 Cd
|
Easy-To-Use
The GA-52Cx and GA-72Cd Locators detect the magnetic
field of iron and steel objects and energized
power lines. Both provide audio detection signals
that peak in frequency when the locator's tip
is held directly over the target. The GA-72Cd
has the option of nulling or peaking
No.
1 Around the World in Performance and Reliability.
Quality
Is Our Hallmark
Schonstedt's underground magnetic locators have
been setting the standards for reliability and
dependability for over 30 years. They are designed
to withstand the rigors of daily on-site usage
and a wide range of environmental conditions.
In fact, the Model GA-52Cx is so rugged and
dependable it's backed by a 7-year warranty
and the
Model GA-72Cd is backed by a 5-year warranty.
Only
two Controls
Designed for one-hand operations, the On/Off-Sensitivity
and Volume controls are located on the underside
of the cover on both locators. This provides
easy access, protects the knobs and contributes
to their overall ruggedness and dependability.
The
GA-72Cd also has easy-to-read digital and bar
graph which displays of signal strength and
polarity. Once you have located a target using
the audio signal, the digital readout and polarity
indicators will help you to visually pinpoint
the target and, in some instances, even determine
its orientation.
Signal
Strength and Polarity Indications
The GA-72Cd's audio signal and the 3-digit LCD
readout will peak, and the (+) or (-) bar graph
will expand to full scale when its tip is directly
over a vertical iron pipe. One end of a horizontal
target will be (+) and the other will be (-).
This difference is very significant because
it helps you to distinguish between vertical
and horizontal pipes.
With the GA-72Cd you can select any one of four
sensitivity settings; the GA-52Cx offers five
sensitivity settings. The GA-72Cd's LCD bar
graph shows the selected gain and the battery
status. The GA-72Cd's headset jack can be connected
to your data logger using a standard stereo
audio plug.
Choice
of Two Audio Modes
The GA-72Cd is configured initially to provide
an audio signal that is always present (Audio
Output switch set to "B"). If you
do not want to hear a signal until the locator
is within the detection range of a target, you
can set the Audio Output Switch to "A".

All Purpose MAC-51B Magnetic and Dual-Frequency
Pipe and Cable Locator |
The
MAC-51Bx (the most cost-effective, all-purpose
locating system on the market) consists of a receiver
and a transmitter that simultaneously transmits
on two frequencies - 571 Hz (LF) and 82.5 KHz
(HF). The receiver has a three position switch
that lets you change modes, "on-the-fly",
between LO, HI, and MAG, for cable and line tracing
with break locating, pinpointing a ferrous metal
target, or identifying and pinpointing an energized
50/60 Hz power line.
In
the LO and HI modes, the receiver's audio signal
provides a sharp null when its tip is directly
over the target. In the MAG mode (no transmitter
required) the audio signal peaks when the receiver's
tip is over the target. You can trace the 571
Hz LF signal conductively applied to any continuous
metal conductor up to 4000 feet. The receiver's
on-the-fly mode-changing feature lets you locate
a complete break using the LO mode, and then
continue on to trace beyond the break in the
HI mode, or trace a metal pipe joined with non-conductive
gaskets.
The
MAC-51Bx by simultaneously transmiting 82.5
kHz (HF) and 571 Hz (LF) signals. This feature
lets you select and compare received audio signals
from both frequencies along with magnetic information
without having to return to the transmitter.
Transmitter
Inductive Mode (HF only)
Induction is achieved by placing the transmitter
over the target cable/pipe or by using the optional
Inductive Signal Clamp. It's the easiest and
quickest way to applying a trace signal that
is strong enough for tracing most lines. The
trace signal generates an alternating magnetic
field around the cable which induces a signal
into the receiver's cable sensor. A sharp null
in the audio signal between the two peaks occurs
when the receiver's tip is directly over the
cable.
Transmitter
Conductive Mode
If an exposed section of a target gas or water
pipe is accessible, conductive coupling is the
most reliable method for applying the trace
signal. This mode has to be used to apply both
HF and LF frequencies so that you can use all
three features on-the-fly. Providing a good
electrical contact between the clip and the
conductive portion of the target line by removing
rust or paint before attaching the clip is very
important.
Magnetic
Locating Mode
Only the MAC-51Bx receiver is required when
operating in the magnetic mode. Just set the
Mode switch to MAG, the Gain control to mid-range,
and you're ready to locate underground ferrous
pipes, water meters, water valves, and property
markers - or anything that has a magnetic field
including the 50/60Hz electro-magnetic field
generated by energized power lines.
