| Zusammenfassung: | Open-loop electrical current sensor for measuring the electrical current flowing in a primary conductor, comprising a magnetic circuit with an air-gap, and a magnetic field sensing device positioned at least partially in said air-gap. The magnetic field sensing device comprises a circuit board, a first magnetic field detector mounted on the circuit board, and a second magnetic field detector. The second magnetic field detector comprises a conductive coil formed on the circuit board, the output signals of the first magnetic field detector and the second magnetic field detector being adapted for connection to a signal processing circuit generating an output signal representative of the primary electrical current. |
