Note. It includes signal fiber demodulator, acquisition software, industrial computer and data transmission module, etc., to realize the acquisition, demodulation, storage and display of fiber optic signals, basic analysis and Data transmission, etc.4 Method OverviewThe basic principle of stress monitoring based on optical fiber sensing technology is to install the optical fiber sensor on the part to be tested of the monitored object. When subjected to stress, the optical fiber sensor will be deformed, causing the parameters of the sensor's output optical signal, such as phase, wavelength or intensity, to change. By demodulating, the change of the corresponding parameter of the optical signal is obtained, and the value to be changed is calculated according to the corresponding relationship or formula between the change and the deformation value. The strain value of the measured part is obtained, and after temperature compensation of the strain value, the stress is calculated according to formula (1), thereby realizing stress state monitoring. σ = E·ε (1) ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 33213-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 33213-2025_English as soon as possible, and keep you informed of the progress.
