Inquiry (采购产品): transducer question I am doing an experiment where i need a transducer to excite a half inch block of aluminum. I dont neccessarily need the transducer to recieve the signal. I was thinking of a basic transducer in the 10kHz range and I was wondering if you had any that you suggested and also the price. thanks for your help Josh Jackson joshjack@umich.edu **** Hidden Message ***** Joshua Jackson 48109 USA Company: University of Michigan E-mail: joshjack@umich.edu **** Hidden Message ***** joshjack@umich.edu
