Temperaturüberwachung mittels fluoreszierender Glasfasern
Core technology for accurate, interference-free transformer temperature sensing
Our Monitoring Solutions
Explore our monitoring solutions, featuring fluorescent fiber optic temperature sensing as our core technology for accurate, interference-free transformer monitoring.
Temperaturüberwachung mittels fluoreszierender Glasfasern
Our primary technology for transformer hot-spot temperature measurement. Fluorescent fiber optic sensors are installed directly on the winding, giving a true reading of the hottest point inside the transformer rather than an estimated value calculated from top-oil temperature.
- Point-type sensing with direct contact on the winding hot-spot
- Completely immune to electromagnetic interference, even near live conductors
- Fully insulated probe suitable for installation inside energized high-voltage windings
- Stable long-term performance with minimal signal drift over decades of service
- Flexible channel configuration to match transformers of different sizes and complexity
