S1808 – Shear wave DPC transducer 250 KHz

Low-frequency ultrasonic transducer for transmitting or receiving the shear-horizontal ultrasonic waves in a broad frequency range from 120 to 340 KHz through-transmission testing.

A general-purpose low-frequency transducer with the nominal frequency of 250 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:
