Abstract：In view of problems of low reliability,poor moisture resistance and short service life existed in electronic sensor applied in steel wire rope tension measurement of mine hoist,a fiber grating sensor was designed.The sensor uses dual-gate structure,and adopts differential compensation method to eliminate impact of temperature;it uses grating detection device to detect center wavelength offsets of fiber grating,so as to calculate pressure of the sensor according to linear relationship between the center wavelength offsets and pressure,namely the tension of the steel wire rope.The experimental and test results verify reliability of the sensor.
