Transmitter to meassure DC current

Hello,

I am looking fpr a transmitter or current transformer to measure 0-40 Ampere DC and get a two wire 4-20mA output. Ideas?

you could use a dc shunt coupled with a millivolt to milliamp converter. or use something liek this

I would lean toward the shunt and mV to mA signal conditioner. We have used this setup in a number of installations. The Phoenix Contact conditioner looks interesting, and says it is rated for 0-50 A. If the equipment layout allowed that to be mounted where you could safely route the high current through it, isolated from other instrumentation, it would be worth looking into.

Use a 0-50 mV (40 A) shunt and the one of these:

6720 or 6740 are ok.
There a lot of brands this is just one out of google search.
