UDV transducers:
program overview
Standard
transducers
|

P = Maximum pressure [bar]
dv = half diverging angle [degree]
|
| Cases |
 |
Custom transducers
Besides standard
transducers, Signal Processing also manufactures transducers based on the user's
specifications, such as piezo frequency and diameter, case dimensions and material,
operating temperature and focus of the ultrasonic beam.
