Abstract

Sensor med en probe 10 innrettet for å måle væskenivået i en tank og for å avgi første elektriske signaler avhengig av dette nivået. Videre omfatter den en elektronisk krets 20 som er koblet til proben 10 og er innrettet til å motta de første elektriske signalene og til å generere andre elektriske signaler som er innrettet for å bli behandlet av et indikatorinstrument 14 som kobles til den elektroniske kretsen 20. Indikatorinstrumentet er innrettet til å anvise informasjon om væskenivået. Den elektroniske kretsen 20 omfatter en kraftutvinningskrets 29, for utvinning av kraftsignaler fra de andre elektriske signalene, hvilke kraftsignaler danner kraftforsyning for sensoren 5.
