AC Analog signal with USB 6001

[electronbas]

I have Hall Effect current transducer to measure AC/DC Current.

If i measure AC current (Switching frequency 1kHz) then it gives mV AC output and if i measure DC current then it gives mV DC output. Can i use NI USB6001 to interface above current transducer ?

Thanks

It would be so much easier to answer your question when you would attach a datasheet of your sensor or atleast provide a link to the (exact!) website of the manufacturer!

Yes, you should be able to use that device as it's input range is +/-10V.

Hi GerdW,

Thanks for your response. link to the sensor datasheet  HS0100T01_R06.pdf (electrohms.com)

I'm using 3 No's of HS100T01 transducer to measure BLDC phase current.

I was wrong you will not be able to use unless you scale the output of that sensor.

The USB-6001 since it only has a +/-10 volt maximum input

and your sensor has a +/-14 volt output.

.

You can probably change the burden resistor on that sensor to lower the maximum output and adjust your scaling accordingly. 

I have to say I have never worked with  current transformer or hall effect with that high of a voltage output. All of my current sensors are scaled in the mV/Amp range.

Hi RTSLVU,

Thank you for your confirmation.

My concern is whether it can measure AC signal or not since its input range is +/-10V without any denotation i.e AC/DC and then If it can measure AC signal then at what max frequency it can support.

Oh.. Okay according to the data sheet the USB-6001 will measure AC or DC voltages (+/-10V) and has a bandwidth of 300Khz.

Usually if an instrument can only measure DC it will only give a positive max input voltage. If it says +/- then it can measure AC voltages.

In all honesty you can probably use that sensor with that DAQ. 3 or 4 volts over range is not going to kill it. (Over voltage protection is +/-20 or +/- 30 volts)  but it will effect the accuracy, specially at higher current levels.

Yeah you are right. But my application wont go beyond nominal current(i.e +/-4V). Then what would be case.
