Fast and easy coating and
wall thickness measurement
The new Sonatest CT-Gage and CT-Gage
DL (data logging) ultrasonic thickness
gauges enable precise and fast wall and
coating thickness measurements. Not only
do both models measure coating and wall
thickness quickly and accurately, from only
one side, but they automatically measure
and eliminate any coating from wall
thickness measurements. This allows users
to locate the finest corrosion and pitting-
without removing the coating.
It is possible to create and store 64 custom
setups for common testing applications.
Switching into the time based B-Scan
view enables a cross section view of the
inspected material. Enabling the high-speed
scan function will give the user 50 readings
per second.
Five user-selected operating modes are
included: coating on, coating off, thru coat
and coating only. All measurements are
temperature compensated. Minimum coating
thickness is 0.0127mm, allowing the gauge
to precisely measure thin coatings with the
advanced waveform analysis technique.
A large backlit graphic LCD features easy-
to-read fonts, graphics and display codes
which show all critical settings.
CT-Gage features include auto probe zero,
auto probe recognition, auto temperature
compensation, and a standalone coating
only mode. The standard pulse-echo and
thru-paint echo-echo modes are standard
features.
The CT-Gauge data-logging model adds
built-in memory, with an RS-232 output
for transferring data to a printer or PC.
Data files can be user-set for a ‘grid type’
structure (data formatted in rows and
columns) or a ‘sequential’ file (all data
appears in a single column).
