New measurement options with diamond magnetic field sensor
The microwave-free, quantum-based magnetic field sensor 'DMFS-C2' from Quantum Technologies' is available from Reichelt Elektronik.
The compact diamond quantum magnetometer enables measurements of physical quantities such as temperature, speed, electric and magnetic fields or even positions and is therefore a precise solution for applications in the fields of materials research, medical technology, industrial automation and basic research. The fiber optic magnetic field sensor uses the latest developments in quantum technology to perform precise magnetic field measurements. Its functional principle is based on the use of the magnetic field dependence of the fluorescence of nitrogen-vacancy centers (NV centers) in diamond. These NV centers are individual atomic defects in the diamond lattice that react sensitively to magnetic fields and are therefore suitable for magnetic measurements.
According to Reichelt Elektronik, what sets the DMFS-C2 apart from other magnetic field sensors are its compact dimensions, its robust housing and the way it works. The sensor head consists exclusively of non-magnetic and non-conductive materials, which ensures reliable and precise measurement regardless of external influences. Even in the high-voltage range, the optical sensor delivers accurate and reliable results in under 20 nanoseconds. Thanks to the isotropic nature of the sensor, the signal amplitude depends only on the strength of the magnetic field and not on its direction. As its surface has the maximum hardness (10), the sensor can also come into direct contact with moving planes. This makes it particularly interesting for use in the processing industry or electromobility.
The sensor is easy to handle: All that is needed for measurements is a simple optical setup with an excitation light source and a photodetector. Microwave radiation or crystal alignment are not necessary.
