Copper alloy wire on -line measuring device and system

The utility model discloses a copper alloy wire on -line measuring device and system belongs to copper alloy wire detection device technical field. The utility model discloses a copper alloy wire on -line measuring system, including paying out machine, admission machine, indisputable element detector and alarm mechanism. Iron element detector sets up on the frame at admission machine place, and indisputable element detector includes tablet and tablet down, goes up the tablet and is equipped with the clearance that the copper alloy wire that is used for treating the detection passed down between the tablet, alarm mechanism is connected with indisputable element detector electricity. When indisputable element detector detected the content more than or equal to 0.03wt% of copper alloy wire chinese railway element, then alarm mechanism started, when the content that detects copper alloy wire chinese railway element when indisputable element detector was less than 0.03wt%, then alarm mechanism closed. The utility model discloses a to the target that copper alloy wire finished product detected comprehensively, the phenomenon of the copper alloy wire come into the market that the iron content exceeds standard has been stopped.
