1.0 INTRODUCTION
The CHECK•LINE® TI-45N 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 measurement sample until it is reflected back towards the
probe from the back side of the material. The elapsed time for this complete cycle is
measured and converted into an accurate thickness reading.
The gauge can be used to measure the extent of corrosion on the opposite, 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 TI-45N 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 thickness readings. The smallest thickness reading will
locate the area of greatest corrosion.
The gauge is supplied from the factory set for an acoustic velocity of 5930 m/sec to
measure steel. The acoustic velocity is easily changed to accurately measure materials
other than steel. Refer to section 6.3 Changing Acoustic Velocity and section 6.1 the
Acoustic Velocity Selection Table. The TI-45N gauge measures thickness in either Inch
(factory default) or mm units. To change units of measure, refer to section 4.1.
The TI-45N is supplied as a complete kit, including the gauge with wrist-strap,
probe and cable assembly, a 2-ounce bottle of coupling fluid (couplant) and a
AA battery — all supplied in a fitted, hard-plastic carrying case.
