4-20 ma current loop

Dear All;
I have a wind sensor i need to interface it with a logger whose input is 4-20 mA type. my sensor gives 0-10 v o/p i want to convert it to 4-20 mA loop so it can be interfaced with my system.


Please Help in this regard.
 

0-1 ma and 4-20 ma input circuit

Have a look at the attached circuit ..
All what you have to do is to reduce the input signal (2-resistor voltage divider) from 0-10 to 0-1, or change the resistor ratio in the first stage ..

Rgds,
