This scanner can be made in different versions, and adapted to the needs of the customer. Two versions was already made: one uses elastic membrane and focused transducer and is intended for spot weld measurement, the second one has much smaller diameter and was made for soft palate measurements.
The system contains following elements:
- Pulser&Receiver (OPGUD);
- UT-card (OPKUD01/100);
- Linear Scanner
- Software package.
