S1844 – longitudinal wave DPC transducer 50 KHz (non-damped, narrow-band)
Low-frequency ultrasonic transducer 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 longitudinal 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:
