Abstract
A device, an ammeter, and a motor vehicle are described. For measuring the electrical current intensity in an electrical conductor (1), at least one sensor means (15) and a first section (10) of the conductor (1) and a second section (20) of the conductor (1) are provided, the directions of the current in the first section and second sections (10, 20) being antiparallel, and the sensor means (15) being situated between the first and the second section (10, 20).
Claims9
A device for measuring the electrical current intensity in an electrical conductor (1) having at least one sensor means (15) and a first section (10) of the conductor (1) and a second section (20) of the conductor (1), the directions of the current in the first section and second sections being antiparallel, and the sensor means (15) being provided between the first and the second section (10, 20).
The device as recited in one of the preceding claims,
- wherein the cross section of the conductor is circular.
The device as recited in one of the preceding claims,
- wherein a magnetic field sensor, in particular a Hall sensor, a lateral magnetotransistor, and/or a magnetoresistive resistor, is as the sensor means (15, 35).
An ammeter having a device as recited in one of the preceding claims.
A motor vehicle having a device or an ammeter as recited in one of the preceding claims.
