1. Overview
Congratulations on your purchase of the Triplett UTG300
Ultrasonic Thickness Gauge. This product is an intelligent
ultrasonic thickness gauge that adopts the latest high
performance and low power consumption microprocessor
technology. Based on the principle of ultrasonic
measurement, it can measure the thickness and sound
speed of metal and other materials. It can detect the thinning
of pipes and pressure vessels after corrosion, and can make
accurate measurements of plates and machined parts. The
gauge can be widely used in petroleum, chemical,
metallurgy, shipbuilding, aviation, aerospace and other
fields.
1.1 Operating Principle
When measuring the thickness, the ultrasonic pulse is
generated by the probe to reach the measured body
through the coupling agent. Part of the ultrasonic signal is
reflected from the bottom of the object, and the probe
receives the reflected echo. The gauge calculates the
round trip time of the ultrasonic wave and the thickness
value according to the following formula, and then
displays the calculated results.
In the formula: H-Measured thickness; V-Material sound
velocity; t-Round trip time of ultrasonic wave in specimen
