TRAVEL SPEED DETECTOR, CONTINUOUS CAST DEVICE

摘要: PROBLEM TO BE SOLVED: To provide a small travel speed detector at low cost capable of detecting the conductor surface by simple structure and further simultaneously allowing level detection to continuous cast device with such detector.SOLUTION: A 1 is constituted so as resonate main coil 21 subordinate 22 provided equal intervals from Za in parallel same current capacitor 3, detect phase difference voltage waveform influenced transfer eddy on surface, based difference, distance resonance frequency resonance, also allow correction distance.
