2.1.3.3 Signal wire
Instrument signal wire consists of rebar sensor signal wire and rust
electrode signal wire. Ports of these two signal wire are on the left of
baffle. Please install according to chapter 4.
2.1.3.4 U-disk
It is used to copy the testing data which saved in the detector into
computer for further analysis.
2.1.3.5 Other fittings
Please see the packing list.
2.2 Testing principles
1. Magnetic testing principle of rebar
The sensor emits magnetic field to part of tested structure, at the same
time, receives induced magnetic field produced by iron-like medium
(rebar) in the scope of magnetic field and then converting to electrical
signals. The host analyzes digitalized signal timely and shows with
various ways such as graphs, data and sound etc to identify rebar
location, cover thickness and diameter precisely, such as figure 2.5.
