Low-frequency dual ultrasonic transducer array for pulse-echo ultrasonic testing of concrete structures by means of shear-horizontal ultrasonic waves.
A general-purpose low-frequency transducer array with the nominal frequency of 50 KHz for the dry-point-contact (DPC) pulse-echo transmitting and receiving ultrasonic waves in highly scattering materials (concrete, wood, stones etc.) by means of dual-aperture arrangement.
Two independent groups of 3 x 4 elements perform transmitting and receiving of longitudinal ultrasonic waves and allow deep penetration and reduced dead zone of ultrasonic testing.
The transducer can be driven by following ACS instruments:
|Transducer type||Dry Point Contact transducer array|
|Nominal frequency||50 KHz|
|Band width||10 to 100 KHz|
|Capacity||3.500 pF ± 100 pF|
|Maximal pulse voltage (bipolar)||400 V (peak-to-peak)|
|Temperature range||-20 to +50ºC|
|Dimensions||139,5 х 105,5 х 83,5 mm|
