Zero Calibration Ultrasonic Thickness Tester For Metallic And Non Metallic Materials MT150

MT150 Digital Ultrasonic Thickness Gauge with EL backlight and low power consumption

Overview

The model MT150 is a digital ultrasonic thickness gauge. Based on the same operating principles as SONAR, the instrument is capable of measuring the thickness of various materials with accuracy as high as 0.1/0.01 millimeters. It is suitable for a variety of metallic and non-metallic materials.

Measuring Principle

The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the material, reflect from the back or inside surface, and be returned to the transducer. The measured two-way transit time is divided by two to account for the down-and-back travel path, and then multiplied by the velocity of sound in the material. The result is expressed in the well-known relationship:


Where: H－Thickness of the test piece.
v－Sound Velocity in the material.
t－The measured round-trip transit time.
