Optical Fiber Temperature Sensing System Design Based on the Spectral Detection Principle

The development of optical fiber temperature sensor in recent years, promoting the development of temperature measurement on line. For example, temperature monitoring in the high-voltage power system equipment to monitor the operational status of their security operation and it plays a decisive role in life too. The system uses semiconductor absorption optical fiber temperature sensor to measure temperature, the range of the temperature measurement at 20°C to 175°C.
