S1820 – dual frequency shear wave DPC transducer 50 KHz / 300 KHz
Low-frequency ultrasonic transducer for transmitting or receiving the ultrasonic shear waves in two operating frequencies for ultrasonic pulse velocity testing and characterization of material properties.
A general-purpose low-frequency transducer with the nominal frequency of 50 KHz and 300 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:
| Transducer type | Dry Point Contact |
| Ultrasonic wave mode | Longitudinal |
| Nominal frequency | 50 KHz and 300 KHz |
| Band width | 20 to 80 KHz and 150 to 400 KHz |
| Capacity | 5000±500 pF |
| Maximal pulse voltage (bipolar) | 400 V (peak-to-peak) |
| Temperature range | -20 to +50ºC |
| Weight | 14 g |
