Overview

MT200Instrument is the intelligent ultrasonic thickness gauge, using the latest high-performance, low-power microprocessor technology based on ultrasonic measuring principle, you can measure the thickness of metal and other materials, and the material velocity can be measured. Monitoring of production equipment in the various pipes and pressure vessels, in the monitoring of their corrosion degree of thinning Also Can To All kinds of sheet metal and machined parts for precise measurements . This instrument Can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

4 Working principle

This Ultrasonic Thickness gauge Measurement of thickness , Is the ultrasonic pulse generated by the probe through the coupling agent to be measured, part of the bottom surface of the ultrasonic signal is an object reflects, the probe from the echo reflected from the bottom surface to be measured, accurately calculate the round trip time of ultrasonic, and according to the following formula to calculate the thickness value and the calculated results are displayed.

In the formula:

H-Measuring the thickness;

v-Materials of sound;

t-Ultrasonic testing of round trip travel time.
