user30585: I want to use a sensor to read pressure in rooms. But sensor like MPX series isn't capable to read air pressure change under 100 Pa. So I want to use industrial sensor like Dwyer 607 Series, and dont have a clue how to connect it to arduino. Anyone can help?
Thanks :)
Fyi, this is the manual instruction for the sensor http://www.dwyer-inst.com/PDF_files/E_76_low.pdf

user4143: That uses the industry standard 4-20mA current loop system. For that you really need a special chip to interface it.
You can buy shields that interface to 4-20mA current loops.
