Ultrasonic nodularity measurement

Determination of the nodularity of cast iron can be done by measuring the ultrasonic sound velocity of the cast iron which is proportional with the sound velocity .
With a mechanical caliper the thickness is measured and at the same time and same spot the ultrasonic time of flight of a short sound pulse is measured.
The materials sound velocity V can then be calculated . V = thickness/ time of flight in meter/second or inches/second

Inspection Technology Europe BV has developed a practical tool to carry out this measurement quick , with minimum effort and accurate.
The system consists of a caliper with water supply system and an utrasonic module.
Ultrasonic coupling can also be done with conventional couplant gel.

The result is immediately visible on a display and the user can set the alarm limits for accept / not accept measurements and optionally store the data in a database.
