Abstract:
    The invention relates to a tension uniformity analyzer of lifter drawing steel line, wherein said tester uses photoelectric detector to collect the vibration period of each steel line, and transforms the period into vibration frequency to be stored into the memory of single chip; based on the function relation between said frequency and tension, calculating out the tension percentage of each steel line; displaying the result on the LED. The invention can avoid force tester and steel rule, with simple operation. And it uses the vibration period to obtain the tension information, with high repeatability. And the single chip can display the result quickly, to improve the testing result.
