temperature data with NI USB 6218

That was what I had in mind. Maybe using the 5V available in the DAQ. Just wondering if there was an example.

Here is a youtube video made for a MyRIO but the concepts are all the same, apply a static voltage, use a resistor and capacitory, and sample accordingly.  They used two analog inputs, one to sample the static voltage applied but if you know this is a static 5V you can probably put a constant in there, and lose some accuracy.

Page 30 of the MyRIO essentials guide goes into more detail.

Hello Mebels,

It is possible to measure temperature from an RTD sensor using your USB-6218. On the following article you can check some connection configurations using 2-, 3- and 4-wires. 

The easiest one to set is the 2-wire connection.

I don't belive the 6218 can act as a constant current source, can it?

If it could it would be listed under the product specifications.
