Study of variable inductance transducers as proximity sensors: II. Experimental study using 'C'-type magnetic circuits
M Macovschi, C Poupot · Measurement Science and Technology · 1990
The authors present experimental results concerning inductance variation of 'C'-type magnetic circuits for proximity sensors, as a function of different parameters: position and geometry of coils, magnetic circuit material, thickness of target, frequency of measuring signal, thermal hysteresis of magnetic circuits and some auxiliary construction elements (protective box, coating resins).
