For laboratory research
Interrogation monitor (FBG)
The FBG interrogation unit FISU – 441 – 1.55-40-Er-IP40 provides registration of optical signals from unified sensor heads based on Fiber Bragg Gratings (FBGs).
The obvious advantage FISU-441-1.55-40-Er-IP40 is possibility software to carry out research performance FBG in the measurements and tests.
