Low-frequency dry-point-contact ultrasonic transducer for transmitting or receiving the ultrasonic longitudinal waves for ultrasonic pulse velocity testing and characterization of material properties.
A general-purpose low-frequency DPC transducer with a nominal frequency of 25 KHz for the dry-point-contact (DPC) excitation or acquiring ultrasonic shear 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 following ACS instruments can drive the transducer:
• A1560 Sonic-LF
• A1220 MONOLITH
