Locating Ferrous and Non-Ferrous Metals
The Rebarscope® uses eddy current sensing and micro-processing
technology, and is ideal for locating ferrous and non-ferrous metals.
Metals located with ease are the following:
• Imperial and Metric reinforcement bars
• Standard copper pipe
• Standard conduit pipe
• Post tension cable (use Rebar mode)
The Rebarscope® allows the user to locate metals by using two
options on the LCD display.
Option 1 – Graphic Bar Display
The action bar displayed on the second line of the location screen
enables the user to determine when the center of the metal bar/pipe
has been detected. When the sensor probe is directly over the
center of the metal bar/pipe, this bar display will have reached its
highest point. When the sensor probe has passed the center of the
metal bar/pipe, the bar display will decrease in size.
Option 2 – Number Display
This option consists of a numerical output value in brackets
displayed on line 1 of the locate cover screen. The range of this
number is 0 to 4095. As the probe moves toward the rebar/pipe the
number will increase. Then when the probe is over the center of the
rebar/pipe you will see the largest number displayed. As you move
the probe away from the center of the rebar/pipe the number will
begin to decrease.
This technique can also be useful in determining whether short or
deep mode is necessary for proper location, cover, and sizing
analysis.
