Abstract

Die Erfindung betrifft einen Tauchankeraufnehmer (1 ) beinhaltend wenigstens eine elektrische, mit Windungen versehene Spule (2) sowie wenigstens einen mit dieser zusammenwirkenden Tauchanker (4), welcher abhängig von seiner Eintauchtiefe in eine Spulenöffnung (6) der Spule (2) eine unterschiedliche Induktivität (L) der Spule (2) hervorruft. Die Erfindung sieht vor, dass der Tauchanker (4) in einem radial äußeren Abschnitt (14) wenigstens teilweise aus einem elektrisch leitfähigen Nichteisenmetall und in einem radial inneren Abschnitt (16) wenigstens teilweise aus einem ferromagnetischen Material besteht.
