4-20 mA current conversion in frequecy

[beymax23]

Hey, is there any possibility to convert the 4-20mA current into frequency, If yes then what  hardware i should use ???

Thanks in advance

How does this pertain to Electrical & Electronics PE exam preparations?

Go review the LM331 (http://www.ti.com/product/LM331). And use a little creatively to convert your current source to a voltage source.

Easy as pie.

BTW, google is your friend.

you can get the frequency spectrum (FFT) of any signal or are you trying to connect a4-20mA sensor to a frequency input?

You can use a 4-20mA to digital converter and use these digital values to convert into freq

something like this will convert 4-20mA into digital https://ncd.io/how-to-convert-4-20ma-current-loop-to-voltage/
