hello
im wanna build a ultrasound transmitter ,receiver circuit (40 kHz).im usin a pair of transducers (gl40t -16f/16s) which look like in figure shown.
1. Does these transducers have any polarity ?
2. can i use a continuos 40khz or should i use bursts ?
3. is there any datasheet for these transducers ?
Instead of randomly using ultrasonic transducers from the garbage pile, why not look a Digikey's or some other supplier's catalog where there are many of them and their prices. You can see the brief specs then look closer at a few of their datasheets for your final choice.
Or if you know who made the ones you are looking at, then go to their website for the datasheet.
i also tried for the same sensor GL-40
i tried a lot in google for datasheet anyone know the datasheet
please post any working circuit diagram or datasheet
