Device for measuring fibre properties in a flowing suspension. The device includes a measuring cell (10) in which there is a measuring field (48) defined between two limiting surfaces and a means (56) of adjusting the width of the measuring field. The limiting surfaces have two opposing, transparent sections (60, 62) that allow illumination through the flowing suspension passing through and measurement by optical means. In addition, the measuring cell (10) has an inlet opening (38) intended for the whole of the suspension flow and an outlet opening (40) intended for the whole of the suspension flow.
La présente invention concerne un dispositif destiné à mesurer des propriétés de fibres en suspension dans un écoulement. Le dispositif comprend une cellule de mesure (10) dans laquelle un champ de mesure (48) est défini entre deux surfaces limites et des moyens (56) permettant d'ajuster la largeur du champ de mesure. Les surfaces limites présentent deux sections opposées (60,62) transparentes qui permettent un passage de lumière à travers la suspension en écoulement, passant à travers, ainsi qu'une mesure à l'aide de moyens optiques. En outre, la cellule de mesure (10) possède un orifice d'entrée (38) et un orifice de sortie (40) destinés au passage de la totalité du flux de suspension.
