Page 8: Product Applications
1.3 Product applications In general, two measurement types can be differentiated: Spot measurement (standalone) For brief quality control, rebar location or metal detection a spot measurement is performed. Spot measurements are done in standalone configuration and provide measurement values, such as concrete cover. For a sequence of spot measurements, the pm app can be used to collect elementary statistics and to attach additional information such as pictures, geolocation to the measurement series. -

Page 10: Measurement Principle
3 Measurement Principle PM8000 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 induced. They produce a magnetic field in the opposite direction. -

4.5 Tracking Indicator It is possible to activate the tracking indicator allowing to visualize the rebar or metallic object. To activate the tracking indicator, the left side key must be short-pushed during the calibration as explained in Figure 11. The deactivation of the tracking indicator follows the same button press sequence. -

Page 22: Pm8000 Measuring Range
4.7 PM8000 Measuring Range The pulse induction principle used by PM8000 has defined operating ranges and accuracies. The measuring range is dependent on the rebar diameter. The expected accuracy of the cover measurement is indicated in the graphic below. (Complies with BS1881 part 204, for a single rebar with sufficient spacing and known diameter). -
Page 23: Measuring With The Cart
When the rebar diameter is unknown, as explained in section 4.6.6, with rebar depth >80mm then the deep mode should be activated. In deep mode, 180mm is the maximum depth limit for detection. Nevertheless, if the rebar diameter is known, the Figure 25 provides more precision on the maximum depth possible of detection following the rebar diameter. -
Page 24: Factors Affecting The Measurement
Figure 27: Measuring range with cart 4.8 Factors Affecting the Measurement 4.8.1 Errors due to Neighboring Rebars All rebars within the sphere of influence 400mm / 16 inch diameter affect the reading. Any ferromagnetic material within the sphere may have an influence on the signal value (e.g. during a calibration). -
Page 25: Resolution
This effect can be reduced by the neighbouring rebar correction implemented in the PM8000 for spot measurement (see 4.6.5 and scan measurements in the pm app software). 4.8.2 Resolution There is a limit to the minimum spacing of rebars, which can be differentiated. This value is depending on the cover depth and rebar diameter. -
Page 26: Factors Affecting Diameter Determination
Figure 30: PM8000 Error of Cover with fixed 16mm rebar diameter setting 4.8.4 Factors Affecting Diameter Determination Rebar diameter estimation is a challenging task with several factors affecting the estimation. It is recommended to measure in several locations to find the best conditions where there is a clean mesh without the presence of overlapping rebars, metallic object or wires/wire connecting first and second rebar layers. -
Page 27: Orientation
Figure 31: Minimum space for rebar diameter measurement Closed welded reinforcement meshes or meshes with binding wires: This produces an additional signal which increases the displayed diameter value on PM8000 sensor or pm app software. Figure 32: Welded or wired rebars 4.8.5 Orientation The strongest signal results are obtained when the vertical axis is parallel to the rebar being measured and the measurement center is directly over the rebar. - Page 28 Midpoint line Figure 33: Sensor positioned at the midpoint line There are 3 methods to find the midpoint lines in both directions: Use PM8000 sensor in spot measurement (locate mode) for locating horizontal and vertical rebars. Then, manually draw the midpoint lines in both directions. The sensor can also locate midpoint lines as described in section 5.3.1.

Carefully read this user manual. Watch all the tutorial videos provided in pm app software or see a demo by a qualified Screening Eagle representative. The test kit is a functional test only. It cannot be used for any quantitative test since the tolerance of the case is too high. -
Page 30: Measurement Process
A circular arrow rotates on the display for approximately 2.5 seconds while the calibration is carried out. Figure 35: Calibration procedure 5.3 Measurement process Generally, a measurement follows the procedure in Figure 36. Figure 36: Measurement process 5.3.1 Finding a Rebar, midpoint line or rebar orientation Place the PM8000 on the test surface and move it slowly in a chosen direction. - Page 31 There are three scenarios. Scenario A: Sweeping Perpendicular to the Rebars The Center Line is in parallel to the rebars This is the correct scenario to detect the rebars. Try it out on the rebar provided in the case, as explained in section 4.8.5. Approaching a Rebar Figure 37: Approaching a Rebar Tracking indicator moves in opposite direction to the PM8000.

- Page 33 The tracking indicator moves in the same direction as the PM8000. The cover value keeps increasing until a maximum value. Continue sweeping until the tracking indicator is exactly at the midpoint Line. The midpoint is directly beneath the Measurement Center (MC). ...
- Page 34 Figure 41: Distinguishing between a Rebar and a Midpoint Scenario B: Sweeping Parallel to the Rebars The Center Line (9) is perpendicular to the rebars. Figure 42: Sweeping parallel Little or no movement of the tracking Indicator. In this case turn the PM8000 by 90° and continue sweeping as described under Scenario A.

Page 35: Map Out The Rebar Grid
Figure 43: Sweeping at an angle Now how to find the check the rebar orientation? Rotate the PM8000 sensor around the measurement center as described in Figure 44. When the PM8000 rotates toward the rebar orientation, the cover value will reduce until a minimum value corresponding to the real rebar cover and real orientation. -
