The working principle of ultrasonic thickness gauge TT100 is described

TT100 ultrasonic thickness gauge is an advanced non-destructive testing instrument that integrates modern electronic technology and measurement technology. It adopts microcomputer to analyze, process and display the data, and adopts highly optimized measurement circuit. It has the characteristics of high measurement accuracy, wide range, easy operation, stable and reliable operation. Products are widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields.
The basic working principle of the instrument:

The ultrasonic pulse emitted by the probe reaches the measured object and propagates in the object, and is reflected back to the probe when it reaches the material interface. The thickness of the measured material is determined by measuring the time of the ultrasonic wave propagating in the material.

The TT100 is ideal for measuring the thickness of metals, plastics, ceramics, glass and any other good superwave conductor.

Nonlinear automatic compensation, the use of computer software to correct the probe nonlinear error to improve the measurement accuracy.

Automatic zero calibration can correct the system error.

It has functions such as coupling state prompt, low voltage prompt, automatic shutdown and so on.

When the measurement thickness of TT130 is less than 100mm, the display resolution is 0.01mm, and other functions are the same as that of TT100.

Suitable for measuring the thickness of steel materials, fixed sound speed 5900m/s, display small unit: 0.1mm.

TT120 adds a high temperature measurement function on the basis of TT110, and the temperature of the measured object can reach up to 300℃.
