Performance characteristics
Firstly, optical fibers have a certain degree of flexibility and can bend within a certain range of curvature radius. Radiant energy can be transmitted along the bent optical fibers, which can detect temperature targets that cannot be directly observed, such as the temperature at the inner wall of containers or pipelines. This is something that ordinary optical path system radiation temperature instruments cannot handle.
At the same time, radiated energy is transmitted through optical fibers, unaffected by external electromagnetic fields, and does not emit electromagnetic interference to the surrounding environment. Moreover, optical fibers have advantages such as insulation and corrosion resistance, making them suitable for working in hazardous areas with strong electromagnetic interference (such as high-power medium and high-frequency induction heating) or flammable and explosive environments.
In addition, the optical cable probe has a compact appearance. If a hole needs to be opened on the furnace wall for temperature measurement, only a small peephole is needed, which is very beneficial for the operation of high-temperature furnaces. It can significantly reduce thermal radiation loss, energy loss, and minimize the impact on the temperature distribution and stability inside the furnace.
