Abstract

Innretningen (40) har en sensor (41) plassert på den første enden (42) av en avlang konnektor (43) ved hjelp av et fast grensesnittledd (79). En registreringsenhet (44) er plassert på den andre enden (45) av konnektoren (43) motsatt den første enden (42). Konnektoren (43) er bøybar innenfor et forhåndsfastsatt kurvaturområde. Når innretningen (40) blir utplassert i sjøen, er den tilpasset for fritt fall gjennom vannmassen og å lande på havbunnen slik at sensoren (41) havner på avstand fra registreringsenheten (44): Lengden av konnektoren (43) er dynamisk variabel innen et forhåndsfastsatt område, for å eliminere eller minimalisere kobling av mulig vibrasjon i registreringsenheten (44) til sensoren (41). Den fysiske adskillelsen mellom sensor (41) og registreringsenhet (44), sammen med de mekaniske egen-. skapene ved konnektoren (43) sikrer at sensoren (41) er i hovedsak vibrasjonsmessig avkoblet fra registreringsenheten (44). Med andre ord vil ikke massen i registreringsenheten (44) hindre sensoren (41) fra å reagere på seismiske bølger, og mulig vibrasjon i registreringsenheten (44) for eksempel på grunn av eventuelle strømninger i vannet som flyter nær registreringsenheten (44) i hovedsak ikke bli overført til sensoren (41). Følgelig utgjør konnektoren (43) en positiv mekanisk forbindelse mellom sensoren (41) og registreringsenheten (44) når det gjelder maksimal avstand, men ikke når det gjelder seismiske eller strømfremkalte vibrasjoner.
