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 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:
|Transducer type||Dry Point Contact|
|Ultrasonic wave mode||Shear|
|Nominal frequency||25 KHz|
|Bandwidth||5 to 35 KHz|
|Capacity||3600 pF ± 50 pF|
|Maximal pulse voltage (peak-to-peak)||± 200 V|
|Temperature range||-20 to +50ºC|
