Introduction
The James® Instruments Rebarscope® utilizes the latest in eddy
current sensing and micro-processor technology to accurately
locate, determine the depth of, and estimate the size of metal
objects in concrete. The eddy current sensor is specifically
designed to react to the outer surface of the metal object only. It is
uninfluenced by small particles in the concrete, whether the
concrete is fresh or hardened, wet or dry.
The Rebarscope® has built-in test modes for rebar/post tension
cable, conduit and copper pipe. The sensor allows the unit to locate
both ferrous and nonferrous metals in concrete.
With an easy to view display, the Rebarscope® provides the user
with an instantaneous structural analysis. The user is aided by
using a graphic bar in the display, and an audio tone to quickly and
accurately locate metal objects. Large numbers in the display show
the estimate of cover. This information can then be used to display
a map of the cover throughout the structure. Further options allow a
2-dimensional cross-section of the concrete under test.
The Rebarscope® was developed for real world application and
everyday durability in mind. It’s rugged and splash resistant case
allows the user to use the Rebarscope® in the field. It’s small but
sturdy sensing probe can withstand test after test with little wear on
the probe face. Additionally, the Rebarscope® is able to
compensate the sensor signal for a wide temperature range; as
may be seen during in-situ field testing.
The Rebarscope® enables the user to store field test data, and later
upload it to a Personal Computer. Once downloaded, the software
allows the user to analyze the data, while a graphing tool function
allows the creation of a contour map.
