Differential measurement of 3-wire current output

Postby Toma Morovic » Mon Oct 05, 2009 12:17 pm

I need to measure a signal from 3-wire current output sensor (4-20 mA) with PICO ADC 24 data logger. I have attached a schematic of a wiring for which I don't know if it is correct. Can anyone please inspect this scheme and tell me can I do it this way or if not, advice me how to do it?

Please help I'm stuck!!!

Hi my colleague has answered your post on the helpdesk, but in the interest of other customers please find attached a diagram of how to wire it up to the ADC24. You would use the single ended input and not differential.

Kind regards
