Abstract
A current detection device for measuring current flowing through a conductor having a magnetic core having a channel for receiving the conductor therethrough, and a magnetic field transducer positioned at least partially within an air gap of the magnetic core. The magnetic field transducer is configured to respond to the presence of a magnetic field by generating an output electrical signal based on a flux density of the magnetic field. The magnetic core comprises an absolute saturation flux density that is substantially lower than an absolute saturation flux density of the magnetic field transducer. Accordingly, a response of the current detection device within the magnetic flux density operating range varies in sensitivity and is substantially non-linear. The response of the current detection device is preconfigured. The current detection device may be implemented in devices and systems where a substantially wide sensing range and relatively high, low-current sensitivity is desired.
