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.A sensor (1) suitable for detecting and discriminating objects comprises: (i) a housing (3) having an opening (11) oriented during use to allow objects to pass therethrough; (ii) at least one light emitter (5) for projecting a band or beam of light (9) over the aperture; (iii) at least one light receiver (15) for detecting the amount of light passing over the aperture. The profile of an object passing through the aperture during use is determined proportionally by measuring the instantaneous change in light level caused by the blocking of the light caused by the passing object. The sensor is useful in detecting and discriminating pre-granules, with particular application for aquaculture.
