Operation Manual for ZBL-R620/R630 Rebar Locator
ZBL-R620/R630 Rebar Locator is designed for the measurement of concrete cover,
bar diameters, rebars distribution and trend.
1. General Introduction
1.1 Basic Working Principles
From its probe the apparatus emits an electromagnetic field into the interior of the test
area, and then receives the induced magnetic field emitted from ferromagnetic media
such as rebars, which is then converted into an electrical signal. The main instrument
system allows real-time analysis and treatment of the electrical signal, displays the signal
in several different forms such as image, data, and sound etc. enabling the correct
determination of rebar location, thickness of concrete cover, and rebar diameter.
1.2 Components of ZBL-R620/R630
ZBL-R620/R630 Rebar Locator is composed of a main instrument body, a probe, a
scan car (ZBL-R630 only) and signal transmission wire.
The probe has direction sensitivity. The signal is strongest when the probe and the
rebar directions are parallel, on the contrary the signal is weakest when the probe and
rebar directions are perpendicular to each other.
The scan car real-time correctly records the displacement of the probe.
Note: when measuring with the scan car, it is better to move the car in a smooth,
uniform motion.
