Low frequency transducers

Does anyone know of a source for low frequency UT transducers. Anything below 50kHz - ideally around 20kHz.

Alternatively, does anyone know how to design such things?

Companies which manufacture ultrasonic cleaners use transducers in this frequency range regularly. You may want to contact Crest Ultrasonics, Sonic systems or Ultrasonic Power corp. All can be found on line I'm sure.

Depepending on what you are looking for, there are several possibilities that I can think of.. Airmar manufactures air and marine transducers in this frequency range. The url is www.airmar.com. The air transducers will be appropriate for aircoupled UT, and the marine (depth/fishfinder) transducers will be appropriate for immersion testing.

Dukane Corporation (www.dukane.com) manufactures ultrasonic welding transducers. These transducers are built for high power and narrow bandwidth. Their suitability for use depends on your application.

Krautkramer (now GE Inspection Technologies) offers several low frequency transducers suitable for NDT in their product line from Germany, though I don't know if they go below 100kHz.

Both Panametrics and Matec have a couple of low frequency offerings but again I don't know if they go as low as 20 or 50kHz.

Hope this helps.

Re: Low frequency transducers

Hielscher (http://www.hielscher.com) manufactures and distributes compact laboratory devices as well as a wide product range of industrial ultrasonic processors of 50 to 16000 Watts for many processes, such as the homogenizing, disintegration, emulsifying, dispersing, deagglomeration and particle size reduction, nano-sizing, sieving and cleaning.
Frequencies are between 90 and 20kHz. All units from 500 to 16,000 watts are running at 20kHz. (see http://www.hielscher.com/ultrasonics/industry.htm)

Re: Low frequency transducers Panametrics does make a X1021 transducer which is a 50kHz narrow band transducer. It, however, is different from that found in the ultrasonic cleaners in that it is not designed for high power output. We typically use the X1021 in pairs for NDT on concrete, wood & other attenuating materials that require the use of low frequencies to penetrate the material.

Hope this helps - Grant

Try to talk to IMG Ultrasuoni; they manufacture low frequency transducers for concrete since 20 years.
