Sumario:An automated system to measure wire tension in MDT tubes is presented.The method uses electrostatic forces between wire and tube to excite mechanical oscillation around the wire harmonic resonance. A LC oscillating circuit is used to measure capacitance variation due towire oscillation. Wire tension is determined by the frequency at which the wirereaches the maximum oscillation amplitude. Both the excitation and measuring circuits are controlled by a computer.
