Hello guys, so i have this transducer sensor which states that the
resonant frequency is 1·8kHz ±0·5kHz
Impedance at resonance 800
Capacitance 25nF ±30%

Okay so my question is how can i determine the minimum frequency it can receive any help on how i can do that?? Thanks.

 

You can test it with a sweep frequency. The minumum will be deterimened by the system quality factor (Q) system noise and the tolerance for errors.

 

okay thank but how do i do this?? is it using an oscilloscope??

 

Sweep frequency using signal generator, and measure the output of the sensor using oscilloscope to check the attenuation. And this is the way I would do it.

 

Okay thank you so much.

 

You really should be able to find the information in the product datasheet.
