2. Measuring Principle
2.1 Measuring Principle
The Profometer PM-6 uses electromagnetic pulse induction technology
to detect rebars. Coils in the probe are periodically charged by current
pulses and thus generate a magnetic field. On the surface of any electrically conductive material which is in the magnetic field, eddy currents are
produced. They induce a magnetic field in the opposite direction. The
resulting change in voltage can be utilized for the measurement.
Coils
Magnetic Field
Concrete
Rebar
Figure 1: Measurement principle
The Profometer PM-6 uses different coil arrangements to generate several magnetic fields. Advanced signal processing allows locating a rebar
as well as measuring of cover and rebar diameter.
This method is unaffected by all non conductive materials such as concrete, wood, plastics, bricks etc. However any kind of conductive materials within the magnetic field (sphere of approx. 200 mm / 8 inch radius)
will have an influence on the measurement.
NOTE! Remove all metallic objects such as rings and watches before you start measuring.
2.2 Calibrated Measuring with Profometer PM-6
The Profometer PM-6 is calibrated to measure on a normal rebar arrangement; which is an arrangement of non-stainless steel rebars fastened with binding wires only e. g. when measuring on welded mesh
wires the cover and diameter readings must be corrected (see “3.7 Practical Hints”). The following information on accuracy, measuring ranges
and resolutions refer to measurements on normal rebar arrangements.
2.3 The
The measuring range is dependent on the bar size. The expected accuracy of the cover measurement is indicated in the graphic below. It
complies with BS1881 part 204, for a single rebar with sufficient spacing.

For the scanning in Y-direction in the Cross-Line Mode the diameter, respectively spacing for rebars running in X-direction can be set in addition.
2)
Settings can be changed in files already stored.
Measuring Range
Select between Standard, Large or Auto ranges (see Figure 2).
NOTE! The range cannot be changed during the measurement. To change the range, store the data first and open a
new file.
Standard is the default setting, because it is the most accurate one.
Auto switches automatically between Standard and Large. Spot should
be selected for measurements on small areas, in corners and on rebar
arrangements with small spacing.
Rebar Diameter Scan-X / Rebar Diameter Scan-Y
Select the Rebar Diameter (6 to 40 mm / #2 to #12, see Appendix A1),
either determined from the drawing or as measured.
Neighboring Rebar Correction Spacing for Scan-X / Scan-Y

Cover and Distance.
Minimum Cover
2)
A Minimum Cover value from 10 to 142 mm / 0.40 to 5.56 inch can be
set in 1 mm / 0.04 inch steps (see Appendix 3). In the Single-Line, MultiLine and Cross-Line Mode/View rebars with less cover than minimum
cover will be shown in red color. In the Single-Line View and Statistical
View a horizontal, respectively vertical dotted line in red indicates the
Minimum Cover value set.
Cover Offset
2)
When a Cover Offset value is set the measured cover will be reduced by
this value; e. g. when a wooden or plastic plate is used to measure with
the probe cart on rough surfaces (see “3.7 Practical Hints”). In this case
the plate thickness must be set as Cover Offset value). A value from 1 to
50 mm / 0.04 to 1.92 inch can be set.
Display Inclined Rebar
By setting this feature the inclined rebar is displayed in the Locating Mode
when all four wheels of the cart have passed over the inclined rebar. In
the Single-Line and Multi-Line Modes it is only shown in the cart symbol.
NOTE! In areas with small rebar spacing this feature may not
work properly.
NOTE! To get smooth color intervals the Minimum and Maximum Cover should be set in 5 mm / 0.20 inch steps.
Sharpen
2)

Maximum Cover
2)
A Maximum Cover value from 20 to 190 mm / 0.80 to 7.48 inch can be
set in steps of 1 mm / 0.04 inch (see Appendix A3). In the Single-Line,
Multi-Line and Cross-Line Mode/View rebars with cover more than Maximum Cover will be shown in grey color.
NOTE! The Maximum Cover must be at least 10 mm / 0.40
inch higher than the Minimum Cover. If not, the instrument
will correct it automatically.
The Maximum Cover should also be set for different files measured on
the same surface to get the same color range for comparison purpose.
Cross-Line Views can be sharpened.
Display Curve
2)
Select Cover Value, Signal Strength or None. The respective curve or
no curve is displayed in Single-Line View.
Align Rebar Positions
2)
When measuring in the Multi-Line or Cross-Line Mode along at least two
lines of at least 55 cm / 22.00 inch length, the rebar positions of the last
line are aligned to the rebar positions of the two previous lines.
NOTE! This feature should only be set, if the rebars are running
parallel to the Start line (X- or Y-line). It is not activated during
the measurements (activated only when storing the data).

With this feature set, the cursor jumps back to the start line when changing line in the Multi-Line and Cross-Line Modes.
Line Height (in Y-direction)
The line height must be set in the Multi-Line, Area-Scan and Cross-Line
Modes. It determines the spacing between the measuring rows. A height
5 to 203 cm / 2.00 to 80.00 inch can be set.
Grid Width (in X-direction)
The grid width must be set in the Area-Scan and Cross-Line Modes. A
width from 5 to 203 cm / 2.00 to 80.00 inch can be set.

Single-Line Mode
PM-630 PM-650
NOTE! It is advisable to locate the first and second layer rebars with the Locating Mode to find the optimum line position prior to measuring with the Single-Line Mode.
The Single-Line Mode is mainly used if cover must be shown along one
line on a rather long distance (e. g. in a tunnel). Therefore the measurements are made across the first layer rebars.
The maximum scan length is 999 m / 3’280 feet in each direction (to the
right and to the left from the zero line).
• Enter the setting menu by tapping on
5

measure the rebar diameter and on completion, it will be displayed
in blue. The measured diameter may be deleted within 5 seconds by
tapping on 6.
• In case the spacing between the rebars is in the range of 5 to 13 cm
(2.00 to 5.20 inch), set the respective Neighboring Rebar Correction
value first (see Figure 26).
The cursor position can be adapted in two ways to changed cart position:
• Tap on the cursor and wait until it becomes white and orange. Move
the cursor to the desired position (even left to the zero line is possible). Be aware: Scanning is not anymore possible between the new
cursor position and the zero-line. Already scanned rebars cannot be
removed by a new scanning but you may scan again on the left of
the first rebar or on the right of the last rebar. To delete the already
scanned rebars tap
• Tap on
and set the required displacement distance. In case you

Area-Scan Mode
PM-630 PM-650
NOTE! It is advisable to locate the first and second layer rebars with the Locating Mode to find the optimum line position prior to measuring in the Area-Scan Mode.
The Area-Scan Mode is mainly used to show the first layer rebar covers
on large areas, e.g. of concrete slabs in car parks. The measuring procedure is the same as for the Single-Line, respectively Multi-Line Mode.
The Area-Scan Mode is best suited for a combination with potential field
measurements; e. g. combined with Canin+ measurements. But in this
case the line height and grid width must be the same for both measurements (square grid required by Canin ProVista).

The Statistics View can be displayed for measurements done and stored
in one of the measurement Modes. It shows the statistical calculation of
the cover values measured.
For measurements with the Cross-Line Mode the statistical evaluation of
the cover readings is done for each layer independently. Hence there is a
Statistical View each for the scanning in the X- and Y-direction.
NOTE! In practice only the cover values and statistical evaluation of the 1st layer rebars (closer to the surface) is of interest.
On the horizontal axis the cover values in the unit set are displayed. The
vertical bars show the percentage of the respective cover values measured and stored. The vertical cursor bar can be moved to any cover value.
The figure on the left of the cursor bar shows the percentage of measured
cover values smaller than the cursor position. The value on the right shows
percentage of measured cover values larger than the cursor position. The
cover value is displayed at the bottom of the cursor bar and at the top the
percentage of measured covers for that cover is shown. Minimum required
cover is shown as a vertical dotted line in red (if set). Covers below the minimum are shown as red bars, covers above the minimum as yellow bars.

The Single-Line View can be displayed if measurements have been
done and stored in the Single-Line, Multi-Line or Cross-Line Mode (not
from Area-Scan Mode). It shows the rebar positions in a cross section.
The rebars are shown to scale depending on the diameter set. To show
them as a circle zoom the horizontal and vertical axis to the same scale.
However, for measurements over a long distance, like in a tunnel the
scale of the horizontal axis will be much smaller and the rebars shown

the same dimensions however create different signals.
The setting of the bar diameter must be slightly higher than the actual

diameter of the mesh rebar. The input depends on the bar diameter and
on the mesh width. This input value should be determined by means of a
test measurement on an open system with specific rebar mesh wire arrangements. Measure on each arrangement with different covers to find
out the diameter setting at which the correct cover is indicated.

NOTE! The “Standard Range” must be selected. With the
“Large Range” or “Spot Range” selected, locating of the
rebars may be completely wrong.
Diameter Measurements on welded Reinforcement Meshes
In most cases a diameter can be measured but the displayed value is far
too large and cannot be used. The only way to determine the diameter is
by an inspection hole.
Measure Rebar Diameter
In case the rebar diameter is not known, the Profometer PM-6 can accurately determine the diameter of a rebar under certain conditions.
NOTE! The Determination of the rebar diameter with Profometer PM-6 is limited to a maximum cover of about 63 mm
(2.50 inch).
The tutorial chapter on the pulse induction principle describes the limitations of the technology and clearly outlines the conditions whereby accurate readings of rebar diameter CANNOT be made if there is too much
interference from neighboring rebars or other metallic objects within the
sphere of influence.
NOTE! In any case, it is advisable to expose at least one first
layer rebar of each rebar arrangement to measure the real diameter. The obtained diameter values can then be compared
and if necessary corrected with the measured real diameter.
Step 1
Step 2
Step 3
Step 4
Locate and mark a rebar grid of the first and second layer
rebars as described under Locating Mode in “3.5 Measurement Modes and Storage of Data”.
Select one rebar that has the largest spacing from neighboring rebars.
Use a ruler and confirm that the spacing is at least as indicated in Figure 26. If not, redo Steps 1 and 2 until a rebar
is located with the required spacing to a neighboring rebar.
15
Place the MC

or
of the Profometer PM-6 over the

However, for accurate cover readings the diameter must be measured
first, thus on each different rebar arrangement. The measured diameter is
to be set prior to scanning the cover. Therefore it is advisable to open for
each area of different rebar arrangement a separate test file and to scan
over rebars only with the same measured rebar diameter.

The diameter displayed for the settings “Metric”, “Imperial” and “Japanese” are shown in Appendix A1.
