1.1 Scope of application

Adopting the theory of ultrasonic wave measurement, TIME TT130 intelligent
Ultrasonic Thickness Gauge possesses the capability of thickness measurement for
various kinds of materials in which ultrasonic wave pulses propagate with a constant
velocity and reflect on the back interface.

The device can be used to perform accurate measurement for various kinds of
plates and parts. Another prominent characteristic of it is to monitor various kinds of
pipes and pressure vessels for the decrease of their thickness during the use
because of corrosion and erosion. TT130 enjoys a wide range applications in many
areas, such as petroleum, chemical engineering, metallurgy, shipbuilding, aviation
and spaceflight, etc.

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.
