Product Function Introduction

GT8050 is a multi-channel fast and high

resolution fiber grating sensor demodulation module

controlled by a PC. It can be combined with random

configuration software, PC and external equipment

to form a Bragg sensor demodulation system and

high-precision Spectral analysis system. The

demodulation module can be applied to various

types of optical fiber sensors. The system draws

a clear and complete spectral pattern according

to the response of the grating sensor to different

temperature conditions, instead of just showing

the deviation of the center wavelength the amount.

 

The demodulation module of GT8050 fiber Bragg grating sensor temperature test system has low cost and high performance, and can be used in various engineering applications and civil applications. The demodulation module is controlled and operated by a PC, which can measure high-precision, large dynamic range.
