Changing transducers
11 December, 2004 - 18:00 — raj
As your discuss about horn making, I have a question.
I wanted my generator supplier to give me variable power. He modified the standard 1500W generator to give 4 outputs like, 200 to 400W, 600W to 800W, 800 to 1200W and 1200 to 1400W.
Here I am using 12 x 50W transducers = 600W, when I measure the voltage across a transducer it varies from 650V to 950V with varying frequency from 16 to 23kHz.
In this situation if I replace 12 pc x 50W transducers to single 600W tranducer and get a booster, how to make a horn for this varying frequency?
Thanks

Hi Raj,
I moved your post here as it wasn't relevant to the original topic. To all users: Please start a new topic on the most appropriate board unless your post is directly relevant to one of the existing topics - thanks.
When you change from 12 x 50W transducers to a single 600W transducer you will almost certainly change the impedance of your system dramatically, and this will require modification or replacement of your generator.
Also, would the 6-transducer system be a cleaning bath by any chance? If so, and you want to change to a probe system that's also a major change - probe systems have much higher Q values and smaller working frequency ranges.
Hence you don't need a horn to cover a varying frequency, you need a generator to suit a single-frequency horn...
In short you need to talk to your generator supplier about getting a suitable generator for whatever transducer, booster and horn you're proposing to use.
