NV Sensor Measurement Systems – Versatile Opportunities

The sensor module for modern precision measurement

Our NV sensor measurement system uses a variety of diamonds with NV centers embedded in a transparent, hardened carrier material. Via optical fibers, the sensor element can be flexibly integrated into a wide range of environments.

• Fully optical & microwave-free: No metallic or galvanic coupling required, ensuring maximum safety at high voltages and full EMC robustness.
• Isotropic and pinpoint measurement: The arrangement and orientation of the NV diamonds enable reliable, direction-independent (scalar) magnetic field measurement, even in hard-to-reach locations such as the air gap of electric motors.
• Temperature- and chemical-resistant: Mechanical housing made of ceramic or glass allows permanent operation between −100 °C and +250 °C; also ideal for aggressive industrial environments.
• Measurement principle: Optical pumping and readout of the fluorescence of the NV centers through the optical fiber – sensitive to magnetic field strength without interference from the sensor element itself.

Typical fields of application:

• Industrial motor and generator monitoring: Precise detection of the magnetic field distribution in rotor/air gap for optimization and safety of drive systems.
• High voltage measurement: Complete galvanic isolation – no risk in high voltages or strong electromagnetic interference.
• Material testing and quality assurance: Non-destructive measurement even on small samples, thin layers, and complex geometries.
• Medical technology, research and development: Contactless measurements even on biological or sensitive samples.
