ABSTRACT:
Systems and devices for testing or inspecting the integrity of package closure seals using contact and non-contact ultrasonic systems wherein a relative movement is created between a package seal and at least one ultrasonic transmitting transducer and at least one receiving transducer such that ultrasonic energy is focused so as to be transmitted toward and along a length of the seal from the transmitting transducer to the receiving transducer in a gaseous environment to thereby monitor energy signals which are analyzed to provide an indication of the seal integrity.
