The dual crystal probes consist of two crystal elements housed in the same case, separated by an acoustic barrier. One element transmits longitudinal waves, and the other element acts as a receiver.

Socket is an electrical interface for connecting to an ultrasonic flaw detector via a probe line.
Aluminum case acts as a support, protection and electromagnetic shielding effect.
Ultrasonic beam is transmitted by the transmitting element.
Receiving element turns a reflected beam from a work piece into an electrical signal.
Sound insulating layer is provided between the receiving element and transmitting element.
Crystal element is bonded to the delay block to change the angle between delay blocks for obtaining the different focus values.

Applications：
"P" Universal Series: Used for general inspection occasions that require high sensitivity and penetration.
"C" piezoelectric composite series: it has the characteristics of high sensitivity, high bandwidth, high resolution and strong penetration. When it is used for the detection of coarse crystal and high attenuation materials, it can obtain very good detection results.
