DESCRIPTION
The BA-OFT200 fiber optic grating temperature sensor detects temperature values through the movement of the center wavelength of the optical signal reflected by the internal sensing element fiber optic grating. It is passive, non charged, intrinsically safe, and free from electromagnetic interference and lightning damage. The temperature measurement accuracy and resolution are not affected by light source fluctuations and transmission line bending losses, and can be directly transmitted remotely through optical fibers.
Product Features
This product is suitable for online temperature measurement of all types of power switchgear static contacts and cable joints and busbars below 500KV. It has an insulation anti pollution and creepage increasing device, completely solving the possible flashover problem of fiber optic temperature measurement systems in high-voltage environments due to fiber optic connection. It ensures that the entire fiber optic temperature measurement system can be used in humid climate areas, coastal areas with severe salt fog, and heavy industry concentration areas Safe operation can also be achieved in environments with severe air pollution.
