Abstract

"REFERêNCIA DE PORTADOR MODULADO POR PERMEABILIDADE". Um aparelho e um método para medir a indutância de um laço de circuito (20), sem referência direta a qualquer constante de tempo ou freq³ência particular. O ruído de baixa freq³ência induzido no laço de circuito (20) é cancelado dentro do circuito detector (24a, 24b), e a diafonia entre vários laços de circuito (20a, 20b) é anulada usando transformadores passivos (22). As novas configurações de laço de circuito (20a, 20b) utilizam a referência de portador modulado por permeabilidade, para proporcionar características indutivas repetíveis com instalações menos intrusivas ou não intrusivas.
