Selection Of The Probe; Treatment Of The Measured Surface - DGC DC-2000C Series Instruction Manual

DC-2000C SERIES ULTRASONIC THICKNESS GAUGE
【7.2】Selection of the Probe
Users can select the suitable probe according to the thickness of the workpiece to
be measured.
Type Freq.
D5008 5.0MHz
D7006 7.5MHz
D7004 10.0MHz
D2012 2.0MHz
D5113 5.0MHz
【7.3】Treatment of the measured surface
When the surface to be measured is too rough or rusty heavily, please perform the
treatment according to the following methods:
1. Clean the measured surface by grinding, polishing or filing, etc. or use coupling
agent with high viscosity for that.
2. Use coupling agents on the work piece surface to be measured.
3. Take multiple measurements around the same testing point.

Application
The probe is used common in
many measurements, for
example when the measuring
surface is flat or with huge
curvature, or the thickness of
the workpiece to be measured
is large than 50mm.
Used in the measurement of
thin wall thickness and small
curvature surface.
Used in the measurement of
thin wall thickness and small
curvature surface.
Used in the measurement of
coarse particles such as cast
iron.
Used in the measurement
when the temperature is less
than 350℃. And High –
℃
Temp. couplant must be
required to use together.
