High precision ultrasonic thickness gauge RG100B is an intelligent ultrasonic thickness gauge that uses the latest high-performance, low-power microprocessor technology. Based on the principle of ultrasonic measurement, it can measure the thickness of metals and other materials, and can also measure the sound velocity of materials. It can monitor various pipelines and pressure vessels in production equipment, monitor their thinning degree after corrosion during use, and accurately measure various plates and processed parts. This instrument can be widely used in various fields such as petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace, etc.

Working principle
The thickness measurement of this ultrasonic thickness gauge is carried out by the probe generating ultrasonic pulses that pass through the coupling agent and reach the measured object. Some of the ultrasonic signals are reflected by the bottom surface of the object, and the probe receives the echo reflected by the bottom surface of the measured object. The round-trip time of the ultrasonic waves is accurately calculated, and the thickness value is calculated according to the following formula, and the calculation result is displayed.
In the formula:
H - Measure thickness;
V - material sound velocity;
T - The propagation time of ultrasonic waves in the specimen for one round trip.
