Measuring small current 0-100 mA and voltage 0-15V with 16 Bit accuracy

Measuring small current 0-100 mA and voltage 0-15V with 16 Bit accuracy

Dear NI,

I am wondering which NI DAQ and accessory would be the best to use for measuring small current 0-100 mA and voltage 0-15V with 16 Bit accuracy.

Hi ParthSingh,

bits define resolution, not accuracy. Can you tell us, in mA, what accuracy you expect?

It is also very important to know what form factor you prefer (USB, Ethernet, PCI), what is the application, how many channels you need etc.

 

What is quite limiting, is the range. Most current AI modules will work with +/-20mA. Something that would potentially suit your task is NI 9227 (you will need a cDAQ chassis to use it; for example cDAQ-9171).

 

We can try to help you here, but I would recommend you to contact you local NI sales representative.
