S1905 – longitudinal wave DPC transducer 25 KHz

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 the 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 transducer can be driven by following ACS instruments:
