Abstract

Et filter (11) forbundet med en måleanordning mens et partikkellastet fluid strømmer gjennom filteret (l 1). Anordninger måler differentialtrykket over filteret (l 1) og sender denne målingen til en styreenhet (21) som inneholder et lager (27) som inneholder målinger av den gjenværende levetiden til filteret (l 1) som varierer lineært med tiden og er korrelert til målinger av differentialtrykk. For hver måling av differentialtrykk frembrakt av en transduser (17) sender styreenheten (21) ut den korresponderende målingen av gjenværende levetid. Dette fortsetter inntil den gjenværende levetiden er lik null. En alarm (26) kan sende ut et lydsignal ved dette trinnet eller ved et hvilket som helst forutbestemt trinn.
