1 Overview

MT160 instrument 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. Production equipment can be a variety of pipes and pressure vessels for thickness measurement, monitoring their use during the corrosion degree of thinning, or all kinds of sheet metal and machined parts for precise measurements. The instrument can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

4 working principle

Ultrasonic Thickness gauges for thickness measurement, is generated by the probes ultrasonic pulse through the coupling agent to be measured, part of the bottom surface of the ultrasonic signal is an object reflects, probes 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-thickness measurement; V-material velocity; T-ultrasonic round trip travel time in the specimen.
