Induktiver Näherungssensor

The distance between sensing coil L1 and object is measured by the pulse width proportional to the phase-shift Ph1 between the coil current and voltage. An analogue comparator K1 measures the coil voltage relative to a reference dc voltage and switches a logic gate when the coil voltage becomes larg...
