Abstract
Et apparat og en fremgangsmåte for måling av tyngdeakselerasjon på bakken, for eksempel tilpasset til geofysiske undersøkelser som benyttes til gruvedrift, omfattende en fundamentramme (31) en resonator (10) som har en første safirskive (2) i et stykke med fundamentrammen (31) og en andre safirskive (1) innrettet med en minimumsavstand fra den første massen (2) og rettet vertikalt inn med hensyn til den første massen (2) slik at de nevnte første og andre skiver (l og 2) danner en resonator for elektromagnetiske signaler (10); en utkrager (41) forbundet med fundamentrammen (31) og som fjærende holder den andre skiven (1) for å tilveiebringe en fast elastisk modus; en magnetisk probe (11) for å påføre et elektromagnetisk signal på nevnte resonator (10) innrettet i henhold til et plan som eksisterer mellom de to skivene (l og 2), en lineær elektrisk probe (12), innrettet under den faste skiven (2) og innrettet vertikalt med hensyn til dens sidekant, for måling av en resonansfrekvens til nevnte resonator som svar på nevnte elektromagnetiske signal, midler for å korrelere variasjonen av nevnte resonansfrekvens til en variasjon av avstanden mellom nevnte skiver (l og 2), og midler for å korrelere variasjonen mellom avstanden og den lokale tyngdeakselerelasjonen. Støtten (7) har variabel lengde for å justere den ueksiterte avstanden d mellom skivene (l og 2). Foretrukket er en første (10) og en andre resonator tilveiebrakt som ovenfor definert koplet og montert på to respektive fundamentrammer i et stykke med hverandre for å måle tyngdeakselerelasjonsgradienten i en vertikal retning. Videre er resonatorene inneholdt i en lukket boks der vakuumbetingelser skapes.
