Time TT100 User Manual

General description

1.1 Scope of applications
The handheld microprocessor-controlled thickness gauge is designed for
measuring the thickness of metals, and non-metallic materials e.g. aluminum,
titanium, plastics, ceramics, glass and any other good ultrasonic wave-conductor
as far as it has two parallel surfaces on the top and bottom.
The TT100 can be used in industrial applications to perform precise
measurements on various kinds of new materials, parts and components, and it
can also be used to monitor various kinds of pipes and pressure vessels for the
decrease of their thickness due to corrosion and/or erosion.
1.2 Basic working principle
The principle of ultrasonic wave in the thickness measurement is similar to that of
optical wave. The ultrasonic wave pulses transmitted by the probe will be reflected
back, while they reach the interfaces. The thickness of the object is determined by
precisely measuring the time the ultrasonic wave travels in the object.
