Abstract

Med en defekt i Isolasjonshylsteret (6) kan ved kjente sonder medium trenge ut av beholderen (2) til sonde- husets (1) innerrom og derfra til omgivelsene og sette personer som befinner seg der i fare eller til og med skade disse. Bondehuset (1) for den nye sonden oppviser et innerrom med to kammere (13,14). Det første kammeret (13) nær beholderen holder stand mot det i beholderen (2) herskende trykk. Den mellom det første (13) og det andre kammeret (14) anordnede gjennomgangsåpnlngen (12) for sensorelektroden (5) eller for dennes elektriske leder lukkes av et bevegelig lukkeorgan (19) eller et stasjonært lukke- organ. I tilfelle av lekkasje på Isolasjonshylsteret (6) trenger riktignok trykk fra beholderen (2) inn l det første kammeret (13), derfra kan det imidlertid ikke forplante seg til det andre kammeret (14) og videre. Slik forhindres at det ved en effekt trenger medium som står under det i beholderen (2) herskende drlftstrykk gjennom sondehuset (1) til omgivelsene og blir til fare for personer som befinner seg der.
