Hi,

I have a sensor which gives voltage output in 0-10v range. But I have no idea about its current range. I have a Data acquisition card which can take input only in 4-20mA current range. How do I convert the sensor output to this DAQ card input range?? How will be the connection? please help me by stating the diagram.

It "works" for the case of 0-5V in giving 4-20mA out. There is a minor calibration error. It would be a somewhat more accurate conversion if the 390k were 400k instead.
