Abstract

PURPOSE: To perform the detection with good reliability, by locating the transmission and reception coils so that they clip the metal strip end, and measuring the strip end position with the change in the induced voltage produced in the reception coil.
CONSTITUTION: The transmission coil T and reception coil R having the coil 13 winding heat resistant wires between the heat resistant coil bobbins 10-1 and 10-2 are opposingly provided with a given distance so that they clip the end of the metal strip S. Further, magnetic field is produced by applying high frequency current to the transmission coil T from the high frequency transmitter 1, and the induced voltage produced in the reception coil R is fed to the display unit 5 via the amplifier 3 and rectifying and smoothing circuit 4. Accordingly, the side end of the strip S can display the induced voltage corresponding to the amount of shield of the reception coil R, allowing to detect with good reliability even under bad circumference with a simple unit.
