1.0 I NTRODUCTION
The CHECK•LINE ® TI-25DL Ultrasonic Thickness Gauge measures the
wall thickness of metals, glass, ceramics and many rigid plastics. This gauge
uses the “pulse-echo” principle of ultrasonic testing where a short ultrasonic
signal is transmitted from the probe. The signal travels through the measure-
ment sample until it is reflected back towards the probe from the back side
of the material. The elapsed time for the complete cycle is measured and
converted to an accurate thickness reading.
The TI-25DL can be used to measure the extent of corrosion on the oppo-
site, inaccessible side of the wall by using the “Subtractive Method.” When
the thickness of the original wall is known, subtracting the thickness reading
obtained from the gauge will determine the extent of corrosion at the point
of probe placement. If the original wall thickness is not known, test readings
should be made along a grid of equally-spaced points to obtain a profile of
the thickness readings. The smallest thickness reading will locate the area of
greatest concern.
The TI-25DL is factory-set to measure steel. The gauge can be easily
adjusted for accurate thickness readings on other materials. Refer to
Sections 6.0 through 6.3. To change the measuring units from inch
(factory setting) to mm refer to Section 4.4.
The TI-25DL incorporates a built-in data logging system which permits the
end user to store up to 1000 measurements in 10 separate batches. The
stored data can be printed or downloaded to a PC using the supplied Data
Transfer Program and serial cable.
2.0 P RECAUTIONS
Do not use the standard probe in applications where material temperatures
exceed 200 °F (100 °C) as the probe will be damaged. Special High
Temperature
Probes should be used. Consult factory.
Keep the gauge free of dust (especially metal powders, carbon, etc.) as they
will damage the gauge. Use a damp cloth to clean the gauge after use.
DO NOT USE CHECMICAL SOLVENTS OF ANY KIND.
