CRD-interrogator-5000HzFBG sensor interrogator unit |
|
product description:
CRD-interrogator-5000Hz is an interrogator unit able to read Fibre Bragg Grating (FBG) sensors' wavelengths. This device provides powerful, reliable, easily integrated measurement options for FBG sensors. The speed, narrow linewidth and excellent repeatability of the integrated optical spectrum analyser provide the accuracy and resolution needed for a wide range of optical sensing applications.
Our main advantage is our customized software, which enables the user to take full advantage of the FBG technology.
