I am currently fighting with an advanced ultrasound application. I am using the T4010A1 ultrasound transducers. My question is whether they have something like a polarity (nothing can be found in their datasheets) and if so, what would be the best way to measure this? There is no indication on the component of it's polarity or a distinction between the legs for example.
Any help is welcome!
Measure with an ohmmeter between each pin and case. If one is connected to the case, that is ground (shield). If neither is, it doesn't matter.
Other than that, there is no "polarity" since they have no DC applied to them (note that).
Ultrasound transducers are normally resonant, narrow-band devices, so polarity isn't normally cared about.
Bumping the thread...
Thjis, where you able find information on that tranducer?
I just acquired two and couldn't find any information as well.
Thanks
As the T4010A1 have a plastic case, it has no polarity.
// Per.
This should only matter if you are driving an array of them. In that case, simply wiring all up the same is sufficient.
Thank you both guys for the info.
Indeed as I did more research, it is just a matter of creating the amplification circuit and driving the transducers with calculations
made inside the MCU.
Thanks again.
