Abstract

Faler (10) for et lavt trykkområde Innbefattende en basisplate av sprøtt materiale 12, en diafragmaplate- enhet (14) montert på baslsplaten (12) og forseglet rundt sin periferi (16) til baslsplaten (12). Trykk Innføres for å bevirke at en midtre dlafragmadel (18) bøyes mot baslsplaten (12) og hvor avbøyning av diafragmaet (18) avføles via strekkmålere (32) for å tilveiebringe en indikasjon av trykket. Diafragmaet (18) er forsynt med flere individuelle understøttelses- tapper eller forhøynlnger (36) på sideflaten til basisplaten (12) slik at når diafragmaet (18) er bøyd mot basisplaten (12) under høyt overtrykk vil under- støttelsestappene (36) understøtte diafragmaet (18) mot bevegelse for å unngå feil eller ødeleggelse av diafragmaet (18). Antall understøttelsestapper (36) kan variere etter ønske. Ved en foretrukket form av oppfinnelsen er basisplaten forsynt med et svært tynt sjikt (40) av silisiumdioksyd, som er en god elektrisk Isolator og som også tjener til å understøtte en lett bevegelse av understøttelsestappene (36) når de berører overflaten til baslsplaten (12) for å redusere spennlngsoppbygningen i diafragmaet (18) ettersom overtrykket øker.
