Abstract
A current sensor is provided for non-invasively measuring electrical current in an electrical conductor. The current sensor includes a housing having a Hall effect device and circuitry for transmitting a signal indicative of the current flowing through the electrical conductor. The current sensor includes a base having a surface for supporting an electrical conductor. A magnetic shielding member is coupled to the surface to shield the Hall effect device from stray or external magnetic fields. A compliant member is coupled to the magnetic shielding member opposite the surface. The compliant member compresses to allow the current sensor to accommodate a large variety of electrical conductor sizes. The compliant member further acts to bias the electrical conductor against the Hall effect device.
