ELECTROMAGNETIC INDUCTION SENSOR AND METHOD FOR MANUFACTURING FOR EASILY CHANGING THE SIZE AND THE SHAPE OF THE ELECTROMAGNETIC INDUCTION SENSOR

摘要

PURPOSE: An electromagnetic induction sensor and a method for manufacturing are provided to easily change the size and the shape of the electromagnetic induction sensor. CONSTITUTION: An electromagnetic induction sensor includes a tube, a coil, nonlinear sensor frames, and a sealing agent. The tube has a straight line type and flexible. The coil is wound with predetermined tensile force. The sealing agent is injected into the sensor frames and sealed. The tube flexible and having a straight line type is mounted at a bobbin shaft of a coil winding machine(s401). The coil is wound around the tube while maintaining predetermined tensile force(403). The tube on which the coil is wound is separated from the bobbin shaft(s415). The tube on which the coil is wound is mounted in the sensor frames(s417). The sealing agent is injected into the sensor frames(s421).
