DESCRIPTION
The BA-OFD series of fiber optic displacement sensors use the principle of measuring micro strain using fiber Bragg gratings to achieve displacement measurement. Through special mechanism design and process packaging, in the state of displacement between the telescopic rod and the measured object, micro strain occurs in the internal structure of the product, causing the wavelength of the fiber grating to become linearly proportional to the micro strain, in order to achieve accurate displacement measurement.
Application Scenario
In industries such as coal mining, civil engineering, heavy machinery, and chemical engineering, safety online monitoring is carried out on the displacement, gap, offset, and wear of mechanisms.
Product Features
Simple layout, can be used in series or parallel with other types of fiber optic sensors for mixed use;
Demodulators for general use with other types of sensors, with good compatibility;
Adopting metallized grating, zero point stability;
Equipped with threaded connection interfaces at the front and back for convenient installation; High precision, high stability, and high reliability.
