Why can they operate normally in environments with strong magnetic fields or high-voltage power grids?
Fiber Bragg Grating (FBG) sensors can operate normally in environments with strong magnetic fields or high-voltage power grids because they are fundamentally optical sensors and do not rely on electrical signals at the sensing point. Unlike traditional electrical sensors that are susceptible to electromagnetic interference (EMI), FBG sensors transmit and receive light signals. This inherent property makes them immune to electromagnetic fields, radio frequency interference, and high voltage, ensuring reliable and accurate measurements in electrically noisy or hazardous environments.
DCYS offers a range of FBG sensors, such as the OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor, which leverages this EMI immunity for various applications.
