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 tested sample
v-Sound Velocity in the material
t-The measured round-trip transit time
FEATURES:
Capable of performing measurements on a wide range of material, including metals, various plastic and ceramics, composite materials, epoxies, glass and other ultrasonic wave well-conductive materials
Four transducer models are available for special application, including for coarse grain material and high temperature applications
