TSENS-FL

FIBER OPTIC TEMPERATURE FLUORESCENCE SENSOR

Reliable long-term temperature monitoring even in electrically demanding environments.

TSENS-FL employs fluorescence lifetime measurement technology to ensure reliable assessment of thermal stress, insulation aging, and operational margins. It is inherently immune to electromagnetic interference, making it suitable for transformer windings, high-voltage equipment, and other power electronic systems. Designed for seamless integration with our D501FL edge device and RM EYE APM, TSENS-FL forms a reliable foundation for continuous, real-time hotspot monitoring.
