The Flaw Hunter UMP 9605 Ultrasonic Testing System is a two-channel system consisting of two 5-MHz immersion probes that are completely interconnected in a special structure inside the water chamber. Due to the high sensitivity required in this test, the Full Immersion technique is used
It is capable of displaying the thickness of a piece, measuring the speed of sound within each piece, and activating optical and audio alarms for inferior parts.
Calculate the exact distance between the two probes, the velocity of sound in the water (1483 m / s), and the specific formula defined in the software of the device, to obtain the thickness of the test components.
In addition, the sound velocity parameter is used to distinguish parts with different mechanical properties.
After obtaining the precise thickness of the piece, by sending an acoustic pulse inside the piece, receiving two consecutive reversing echoes from behind the piece, adjusting two different gates on them and using the special formula, the device is able to determine the sound velocity within the piece is desired.
For this purpose, the exact velocity of sound in each segment is matched to the tables in the device memory, then the mechanical properties of each segment are extracted and the defective parts separated.
This separation is very useful without damaging the parts, especially in Ductile Iron Castings to Verify Nodularity.
