PC  

       -        Optional thermal mini- printer to print the          
                measured data via RS-232 port. 
 

1.3 Measuring principle 
 

The digital ultrasonic thickness gauge determines the 
thickness of a part or a structure by accurately measuring  
The time required for a short ultrasonic pulse generated by 
a transducer to travel through the thickness of the material, 
to reflect from the back or inside surface and be returned 
to the transducer. The measured two-way transit time is 
devided 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 following relationship:
