hello everybody,
At work i am asked to develop a mean of detection the flow of current in a conductor. The current is DC current, should be about 50mA.
I've tried many different configuration to build a "kind-of" current transformer, with 5 to 10 turns around the conductor under test. the two free leads of the pick-up coil are connected to a resistor, and fed to an op-amp..
I've tried many different configurations, but i don't seem to be getting satisfactory results.. no clear voltage change with respect current change. (i just want to detect a variation between 0 mA and 50 mA)..
So before i post a schematic of my trials and share it here.. can anybody experienced tell me if it is doable at all?
It should be since DC current clamps exists...
I'll keep on trying.. waiting for some response-advice from your side.. i am really lost on that project...
