Patentkrav
1. Trådløs antennesammenstilling (10) for trykksikkert instrumenthus (100), hvori et måleinstrument (200) forsynt med en fremskutt trådløs instrumentantenne (201) er innrettet eller integrert inne i det trykksikre instrumenthuset (100), hvilken trådløse antennesammenstilling (10) er fysisk og galvanisk adskilt fra den trådløse instrumentantennen (201), karakterisert ved at:
- den trådløse antennesammenstillingen (10) omfatter minst en ytre antenne (20) innrettet ved ytre overflate av det trykksikre instrumenthuset (100) og minst et indre antenneelement (40) innrettet inne i det trykksikre instrumenthuset (100), hvori både den minst ene ytre antennen (20) og det indre antenneelementet (40) er elektrisk isolert fra det trykksikre instrumenthuset (100),
hvori den trådløse antennesammenstillingen (10) fungerer som en elektromagnetisk trådløs signalforlenger for instrumentantennen (201) hvilken overfører et elektromagnetisk kommunikasjonssignal fra det interne måleinstrumentet (200) til det ytre av instrumenthuset (100) ved at det minst ene indre antenneelementet (40) er innrettet for overføring av det elektromagnetiske trådløse signalet til den trådløse instrumentantennen (201) til den minst ene eksterne antennen (20).
2. Trådløs antennesammenstilling (10) for trykksikkert instrumenthus (100) i samsvar med krav 1, karakterisert ved at den minst ene ytre antennen (20) er dannet av en metallring (21) eller minst en metallknapp (22) innrettet ved ytre overflate av det trykksikre instrumenthuset (100) og elektrisk isolert (30) fra det trykksikre instrumenthuset (100).
3. Trådløs antennesammenstilling (10) for trykksikkert instrumenthus (100) i samsvar med krav 1, karakterisert ved at det minst ene indre antenneelementet (40) er festet i forhold til det trykksikre instrumenthuset (100) og elektrisk isolert (41) fra det trykksikre instrumenthuset (100), samt strekker seg over den trådløse instrumentantennen (201) og mot den minst ene ytre antennen (20) og i kontakt med den minst ene ytre antennen (20) eller ender i umiddelbar nærhet av den minst ene ytre antennen (20).
4. Trådløs antennesammenstilling (10) for trykksikkert instrumenthus (100) i samsvar med krav 3, karakterisert ved at det indre antenneelementet (40) er et ledende langstrakt element, så som en metallpinne eller metallwire.
5. Trådløs antennesammenstilling (10) for trykksikkert instrumenthus (100) i samsvar med krav 4, karakterisert ved at det indre antenneelementet (40) er innrettet for låsing av orienteringen til måleinstrumentet (200) i forhold til det trykksikre instrumenthuset (100).
