Abstract

La présente invention présente une nouvelle technique d'encapsulation qui permet l'utilisation d'une plus grande plage de matériaux d'isolation pour des capteurs de conductivité par induction, ce qui permet de réduire significativement le coût de production des capteurs, d'améliorer leur précision et exactitude, et d'augmenter leur sensibilité.
