AC current sensors with interface...

[Geir Holmavatn]

Hi,

I'm looking for non-contact current sensors for 0-60/70A AC connected to
some digital interface (1-wire, GPIB, RS422, ethernet etc). The
measured cable should run through a hole in the sensor and not be
galvanically connected.

I need to monitor and register AC current with a computer from different
appliances...

Thanks for comments and tips on where I can find such sensors..

regards Geir

You need a CT "Current Transformer"

They also have HALL devices with integrated components to give you a
0..10V output for current..
