Blade load vibration measurement system Molas FD Measuring range ±1500με
1,Summary
The system consists of a demodulator and sensors. The sensor converts the measured signal into a wavelength signal through a fiber grating, which is divided into a load sensor, an acceleration sensor, and a temperature sensor. The demodulator is responsible for demodulating the feedback wavelength of the sensor and transmitting data to the outside. The demodulator is used in conjunction with different sensors, and the sensor is arranged at the position to be measured on the blade, which can realize the measurement of the load, vibration and temperature of the blade.
