    I am looking for piezo transducers with the following specs:
    Resonance frequency 10.5khz
    Resonant Resistance: 400 Ω
    Capacitance 12,000pF@100Hz
    Disc diameter:~15mm

    I do not have much of an electrical background therefore, I have been having trouble locating those type specs. I have found however, these on eBay:

    Resonant Frequency: 6.8 ±0.7kHz
    Resonant Resistance: 300Ω Max
    Capacitance: 15,000pF ±30%
    Disc diameter: 20mm

    Also, I found a guy that sells some with the following specs:
    Resonant Frequency: 6.5kHz Resonant Resistance: 500 Ω
    Capacitance: 14,000pF
    External Diameter: 20mm

    What do you think, folks ? I'd like to find specs that match the first transducer. If the specs are close, can they be easily tweaked ? Thanks a lot guy ?

    You cannot tweak the qualities of the transducer, but maybe you can adapt your application to use the specs of the new transducer.

    What are you trying to measure and what are you trying to measure it with?
