U-disk through Data Output and then analyze the data in U-disk with
computer software.
2.1.1.5 Sensor port
It is used for connecting with sensor signal wire.
2.1.1.6 Nameplate
On the back of instrument and sensor, nameplate consists of company
name, manufacture date, instrument serial number etc.
2.1.2 Sensor and electrode
2.1.2.1 Rebar sensor
With an integrative design, rebar sensor as shown in fig.2-2 can scan
rebar and record displacement of sensor in real time accurately. While
going forward, sensor scans rebar and backward, scrubs it.
Figure2.2 Rebar sensor
Sensor is directive. When sensor axis parallels with the direction of
rebar, it is most sensitive, conversely, when sensor axis is
perpendicular to the direction of rebar, the signal is weakest. Therefore,
while measuring, sensor axis should be parallel with the direction of
rebar and scans in the vertical direction.
