Abstract

PURPOSE: To approach the distance to output voltage ratio of a detecting coil and the object to be detected to a linear shape in a circuit of detecting the output of the oscillating section changing according to the characteristics of the detecting coil, by inserting a nonlinear element between the detecting coil and the oscillating section.
CONSTITUTION: When high frequency current is flowed to a detecting coil 2 and the object to be detected is approached to its detecting end, the characteristics of the detecting coil 2 change according to the distance between the object to be inspected and the detecting coil 2. According to this, the oscillating output of an oscillating section 3 changes and the output thereof is sent out to a detecting output section 4, by which it is detected and an output voltage E0 is generated. At this time, the nonlinear element 5 inserted between the detecting coil 2 and the oscillating section 3 offsets the nonlinear output characteristics by a tracing detector. Hence, if various constants of the circuit are properly selected, the approximately linear output characteristics may be easily obtained.
