FluoroSenz Fiber Optic Temperature Monitoring System

FluoroSenz Fiber Optic Temperature Monitoring System conducts real time monitoring to accurately measure point temperatures of hotspots in Transformers, Switchgears, Generators. It is designed specifically for use in harsh environments with High Electric and Magnetic fields. The system is based on Calibration-free Fluorescence Time Decay Technology, which eliminates the need for sensor recalibration over the sensor’s lifetime.
