A general-purpose low-frequency transducer array with the nominal frequency of 100 KHz for the dry-point-contact (DPC) transmitting or receiving ultrasonic waves in highly scattering materials (concrete, wood, stones etc.).
The 12 element DPC array perform transmitting or receiving of longitudinal ultrasonic waves. A couple of M2103 allow through-transmission of very thick components (up to 5 meters).
The transducer can be driven by following ACS instruments:
