Abstract

En sensor omfatter to identiske vibrerende elementer som virker med en felles arbeidsfrekvens og forbundet til hverandre ved en mekanisk frikoblingsanordning. Anordningen omfatter en ramme av to forbindelsesbroer som hver støtter ett element. Rammen omfatter en rekke av massedeler og fortynnede deler slik at frekvensen til en modus av den strukturelle resonansen til rammen er hovedsakelig lik den felles arbeidsfrekvensen og hver forbindelsesbro er tilveiebrakt i en vibrasjonsnode av rammen ved den felles arbeidsfrekvensen. Dermed er vibrasjonene til de to vibrerende elementene frikoblet fra hverandre. 1
