Portable Digital Ultrasonic Thickness Measuring Instrument UT-1 Tester Device
Primary Theory:
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 form 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.
Features:
3.1 Capable of performing measurements on a wide range of material, including metals, plastic, ceramics, composites, epoxies, glass and other ultrasonic wave well-conductive materials.
3.2 Can collocate variety different frequencies,wafer sizes of probes;
3.3 Sound Velocity Calibration function as a known thickness;
3.4 Coupling status indicator showing the coupling status;
3.5 EL backlight, and convenience to use under dark environment;
3.6 Have the battery indicator function, can real-time display the remaining power
3.7 Auto sleep and auto power off function to conserve battery life;
3.8 Smart, portable,high reliability, suitable for bad environment, resist to vibration, shock and electromagnetic interference.
Introduction
Ultrasonic Thickness Gauge will be the best choice for accomplishing measurement. It fits many kinds of metal, such as steel, cast steel, aluminum, plastic, China glass, glass fiber and any other good conductors of ultrasonic. The gauge can provide quick and accurate measurement to various work pieces such as sheets of board and processing parts. Another important application of the gauge is to monitor various pipes and pressure vessels in production equipment, and monitor the thinning degree during using. It can be widely used in petroleum, chemical, metallurgy, shipping, aerospace, aviation and other fields.
