Abstract

Whole optic fiber weighing technique and its device of belt conveyor are developed and put into application. Four FBG stress cells support a frame in a belt conveying line. In each cell, two FBG strain gauges are respectively installed at the stretching and compressing places to get the effects of sensitivity enhancement and temperature compensation. The weighing signals are from both FBG wavelength shift of loading cells and fiber belt speed meter. By means of integral algorithm, the weighing result is obtained. Actual coal weighing test shows that the accuracy of this weighing device is under 0.5%.
