'[ee] Sensor using toroid and Hall effect'
Anybody know a source of current sensor using a ferrite toroid with a
Hall sensor integrated ?

We used to use one made by honeywell that worked to about 900A DC but
I don't have much more info than that.
The LEMS ? current sensors also use this sort of sensor to derive a
feedback signal so if you need it for a specific project you may be
able to use parts of one of these.

No, but NVE's giant magnetoresistive sensors are supposed to be so
sensitive that placing one over a trace on a PCB will allow reasonable
measurement of the current through the trace running under it.
YMMV. I've never tried it.
