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 150 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:
| Transducer type | Dry Point Contact |
| Type of generated wave mode: | Shear-horizontal |
| Nominal frequency | 250 KHz |
| Band width | 60 to 220 KHz |
| Capacity | 980 pF ± 100 pF |
| Maximal pulse voltage (bipolar) | 400 V (peak-to-peak) |
| Temperature range | -20 to +50ºC |
| Weight | 14 g |
