Low-frequency ultrasonic transducer array for transmitting or receiving the longitudinal ultrasonic waves in a broad frequency range from 20 to 80 KHz for ultrasonic pulse velocity testing.
A general-purpose low-frequency transducer with the nominal frequency of 50 KHz for the dry-point-contact (DPC) excitation or acquiring shear-horizontal ultrasonic waves in highly scattering materials (concrete, wood, stones etc.)
It can be used in ready-made housing with the Lemo00 plug or non-wired for self-tailored applications, e.g. for customization of transducer arrays by the customer.
The transducer can be driven by following ACS instruments:
|Transducer type||Dry Point Contact|
|Nominal frequency||50 KHz|
|Band width||20 to 70 KHz|
|Capacity||1.700 pF ± 100 pF|
|Maximal pulse voltage (bipolar)||400 V (peak-to-peak)|
|Temperature range||-20 to +50ºC|
