Abstract: A current sensor includes a magnetometer. The magnetometer includes a sensor element including at least one paramagnetic center that generates fluorescence radiation, a radiation receiver configured to receive the fluorescence radiation from the sensor element and generate a first electrical signal based on receiving the fluorescence radiation from the sensor element, and an electronic output circuit configured to generate and output a second electrical signal based on the first electrical signal. The value of the fluorescence radiation generated by the sensor element depends in part on a magnetic flux density at the location of the sensor element. The magnetometer is configured to be placed near or in direct contact to a wire carrying a current such that the current in the wire modifies the magnetic flux density at the location of the sensor element.

Abstract: A scalar magnetometer includes a sensor element, a circuit carrier, a pump radiation source, a radiation receiver and evaluation means. The pump radiation source emits pump radiation. The sensor element preferably includes one or more NV centers in diamond as paramagnetic centers. This paramagnetic center emits fluorescence radiation when irradiated with pump radiation. The radiation receiver converts a intensity signal of the fluorescence radiation into a receiver output signal. The evaluation means detects and/or stores and/or transmits the value of the receiver output signal. The material of the circuit carrier is preferably transparent for the pump radiation in the radiation path between pump radiation source and sensor element and transparent for the fluorescence radiation in the radiation path between sensor element and radiation receiver. The components sensor element, pump radiation source, radiation receiver and evaluation means are preferably mechanically attached to the circuit carrier.
