Multiple Echo Modes (IE EE) LED Screen Digital Through Coating Ultrasonic NDT Thickness Gauge

Scope of Application

This thickness gauge adopts multiple echo modes (IE, EE), which can measure the thickness of the product through a certain coating thickness. This instrument can be equipped with a narrow-pulse ultrasonic thickness measuring probe, which can use the E-E mode to pass through the coating layer, the rust layer, and accurately measure the thickness of the workpiece body between 3-20mm, and the thickness measurement accuracy can reach 5μm; It can also be equipped with ordinary thickness measuring probes, whose detection range can reach 0.65mm~500mm. This instrument can accurately measure various plates and various processed parts, and can be widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.

Basic Principles

The principle of ultrasonic thickness measurement is similar to that of optical wave measurement. The ultrasonic pulse emitted by the probe reaches the measured object and propagates in the object. When it reaches the material interface, it is reflected back to the probe. The thickness of the measured material is determined by accurately measuring the time of ultrasonic propagation in the material.

Instrument Features

• Three measurement modes, P-E I-E and test, are adopted to accurately measure the thickness; I-E mode enables the gage to measure thickness through coating;
• high precision timing chip and v-path calibration model are adopted, with wide measurement range and high measurement accuracy;
• the measurement information can be completely stored, including thickness measurement value, measured sound velocity and time information;
• two No. 5 alkaline batteries are used for power supply;
• the display resolution is 0.01mm, and the error limit is 0.4% H (H is the thickness of the working piece);
• the contrast of liquid crystal display is adjustable, and has LED backlight display, which can be used in various light environments.

Main functional parameters

• it has zero calibration, which can automatically correct the system error;
• if the thickness is known, the sound velocity can be measured back to improve the measurement accuracy;
• it has the coupling state prompt function to intuitively grasp the measurement state;
• it has the power indication function, which can display the remaining power of the battery in real time.
