However，the complex structure and harsh environment make the wire rope occur broken ， corrosion ，abrasion and other faults. These faults will be a danger to the operator and device if we do not discover them in time. Broken wire is one of the most common and most difficu lt to forecast in these faults. 1n present ，people still use original eye-measurement method and replace wire rope regul arly in the field of wire rope inspection ，these methods not only get inaccurate result but also cause serious waste of the resources. So，an intelligent measuring instrument [or the broken wire must be mad巳 no delay. Based on the deep research on the domestic and international research for broken wire rope inspection ，we find that magnetic flux leakage testing method which checks the broken wire rope by mean s of magnetic flux leakage is more often used. However，this method exist flaws in weak magnetic flux leakage recognition because of bI讪cen wire coming from interior.This paper is designed a new broken wires testing sensor-a solenoid-monitoring sensor detecting broken wire.

Meantime，the merits and demerits of the present broken wire rope testing method are analyzed and a new prin ciple for testing method is presented in the paper. Secondly，this paper ma inly research es the testing prin ciple about the n ew broken wires testing sensor-a solenoid-monitoring sensor detecting broken wire.
