Abstract

Metode og utstyr for deteksjon og bestemmelse av mengden av partikler som befinner seg i eller utfelles i en væske, f.eks. asfalten som utfelles i olje. Væsken sirkuleres igjennom en gjennomlysbar celle (7), idet konsentrert, sterkt lys tilføres fra en lyskilde (8) på den ene siden av cellen (7), mens et digitalt kamera (4), via sterk forstørring (5,6), opptar bilder fra motsatt side av cellen. Billedsignaler fra kameraet sendes til en databehandlingsenhet (10) med skjerm (11) for visuell deteksjon og/eller videre bearbeiding av signalene for bestemmelse av partikkelmengde etc.Method and equipment for detecting and determining the amount of particles contained in or deposited in a liquid, e.g. the asphalt precipitated in oil. The liquid is circulated through a translucent cell (7), with concentrated, strong light being supplied from a light source (8) on one side of the cell (7), while a digital camera (4), via strong magnification (5,6), occupies images from opposite side of the cell. Image signals from the camera are sent to a data processing unit (10) with screen (11) for visual detection and / or further processing of the signals for determination of particle quantity etc.
