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.

Purchase guideline

The table below is aimed to help you choose which transducer to purchase for which application.

Ultrasonic Frequency
Piezo Diameter
 Characteristic Application
Low
Low
 Small near field area High velocities in narrow area
Low
High
 High sensitivity Measurements in highly attenuating liquids, far from transducer, high velocities
High
Low
 Small ultrasonic beam radium near transducer Low velocities close to the transducer
High
High
 Less diverging ultrasonic beam Measurements far from transducer of low velocities in non attenuating liquids

In addition, one has to know that:

Ultrasonic Frequency
 Characteristic Application
Low
 Long time burst; noticeable ringing effect Measurements in attenuating liquids; high velocities
High
 Short time burst Measurements with a high spatial resolution

and that

Piezo Diameter
 Characteristic Application
Low
 Low sensitivity; small near field Measurements close to transducer
High
 High sensitivity, long near field Measurements far from transducer
