| Abstract: | A new intersect system which will be used in tube creeper isintroduced,a static magnetic intersect system.The system is comprised by magnet,Hall element,signal distinguish and processing circuit.There are magnetic leakage inside tube with a strong magnet.Make use of small signal can intersect position of solder joint.This kind of intersect system has several features:higher intersect precision, safety and reliability, easy to handle and lower price. |
