There are several types of fiber optic temperature measurement

Fiber optic temperature measurement can be applied to different projects, including fluorescent fiber optic temperature measurement, distributed fiber optic temperature measurement, and fiber optic grating temperature measurement.

1. Fluorescent fiber optic temperature measurement

The fluorescent fiber optic temperature measurement scheme is gradually recommended for switchgear. In addition, large oil immersed transformers, high-voltage reactors, etc. need to use fluorescent fiber optic temperature measurement methods. However, traditional measuring instruments are prone to bias due to high voltage and strong electromagnetic interference (EMI). Fuzhou Huaguang Tianrui's fluorescent fiber optic temperature sensor has inherent insulation characteristics, allowing for precise online temperature monitoring of components that withstand high voltage or strong currents.

2. Distributed fiber optic temperature measurement

The distributed fiber optic temperature measurement system adopts advanced optoelectronic technology, communication technology, microprocessor technology, digital temperature sensing technology, and uniquely designed low-temperature, strong electric field, and humid environment operation technology. It can monitor the temperature in different environments separately, detect accident hazards early, and minimize losses. At the same time, it can also provide a large amount of online monitoring data, providing reliable basis for operators to comprehensively understand the operation of heating pipelines.

3. Fiber Bragg Grating Temperature Measurement

The fiber optic sensing analyzer adopts high-power laser light source and high-speed multi-channel parallel light detection technology. Compared with traditional ASE light source technology, the output light power of the light source is over 85%, the output power of the light source is increased by more than 100 times, and the power consumption is reduced by 50%. The effective service life of the light source is increased by more than 10 years. It can accurately detect weak fiber optic grating sensing signals caused by fiber optic transmission line losses or cascaded losses of optical splitters in engineering sites.
