The FBG displacement sensor uses a fiber Bragg grating as its sensing element and measures wavelength signals rather than electrical signals, so it can still operate in strong electromagnetic fields and nuclear radiation environments. The measurement range of Fibot-D-01 is 100 mm, the resolution is 0.1% F.S., the accuracy is 0.5% F.S., the center wavelength covers 1510 to 1590 nm, and it is equipped with a 3 mm armored optical cable. The all-metal packaging and built-in temperature compensation make it easier to install and maintain in outdoor or long-term monitoring scenarios, and the reusable sensing unit also reduces spare parts pressure during multi-point deployment. In addition to the standard range, we support customization of other displacement ranges. For information such as price, packaging, MOQ, and delivery time, please contact us to confirm, and we will assist with a quotation based on the project quantity and installation requirements.

FAQ
What environments are FBG displacement sensors suitable for?
It is suitable for industrial displacement monitoring, structural displacement monitoring, and strong electromagnetic field and nuclear radiation environments. Because it adopts the fiber Bragg grating wavelength modulation principle, the measurement signal is not subject to electromagnetic interference, and the sensor body does not require power supply, making it easier to deploy in sites where power supply is inconvenient or the electromagnetic environment is complex.
What is the standard range of Fibot-D-01? Can other ranges be customized?
The standard range is 100 mm, the resolution is 0.1% F.S., and the accuracy is 0.5% F.S. Other displacement ranges can be customized; please contact us to explain your measurement range and installation requirements, and we will assist in confirming them.
Does this sensor require an external power supply?
The sensor body does not require a power supply; it is a passive measurement. On site, only a matching fiber Bragg grating demodulation device is needed to read the wavelength changes, and the wiring is relatively simple.
What information is needed when purchasing?
Please provide the measurement range, installation method, required quantity, project location, and whether a matching demodulation device is needed. Based on this information, we will assist in confirming the configuration and provide a quotation.
