description PURPOSE:To measure the axial tension of a rail by a magnetic anisotropic detection sensor, by averaging four peak output values accompanied by magnetic anisotropy yielded by stress, based on the output of the magnetic anisotropic sensor, and performing correction based on the temperature. CONSTITUTION:A rail axial tension detecting sensor 17 is attached to a rail. When an anisotropic sensor 8 is rotated, signals are obtained for 0 deg.-360 deg.. Four peak values are detected by a peak value detecting circuit 26. Said peak value data are sequentially added, and an average value is computed by an average value circuit 30. The corresponding rail axial tension is read from said average value by a converter 31 and displayed on a display device 32. The value of the rail axial tension is corrected by the temperature data from a thermometer 18 in a temperature correcting circuit 33 so as to obtain the value of the standard temperature. The value is compared with upper and lower limit values in a comparator 34. When the value exceeds the limit value, a signal is outputted and displayed on the display circuit 32.
