Abstract

En sensor (1) passende for detektering og diskriminering av gjenstander omfatter: (i) et hus (3) med en åpning (11) som under bruk er orientert for å tillate objekter å passere derigjennom; (ii) minst en lysutsender (5) for projisering av et bånd eller en stråle av lys (9) over åpningen; (iii) minst en lysmottaker (15) for detektering av mengden av lys som passerer over åpningen. Profilen til et objekt som under bruk passerer gjennom åpningen bestemmes forholdsmålsmessig ved måling av momentanforandringen i lysnivå forårsaket av sperring av lyset forårsaket av den passerende gjenstand. Sensoren er anvendbar ved detektering og diskriminering av forgranulat, med særlig anvendelse for aquakultur.
