Functional Features

1. High precision, high reliability

2. Essentially safe, it can be applied under harsh conditions such as strong electromagnetic interference, high lightning strikes, flammability, and explosiveness

3. Quasi distributed measurement, multiple sensors can be connected in parallel on a single optical fiber

4. Simple layout, can be mixed with other types of fiber Bragg grating sensors
