Abstract

The invention concerns a method and arrangement for recording the condition of a suspension in motion, which suspension can contain fractions with particles of very different sizes. The suspension is illuminated by a beam of light. Light received from the suspension is detected in order to produce an electrical signal corresponding to the detected light intensity. The illumination of the suspension is carried out with a narrow beam of light in relation to the space between large particles. Light received from the suspension is detected within a narrow angular area. An extreme value Vp of the electrical signal is indicated within a previously determined interval of time. Within each interval of time the extreme value forms the reference value for calculating pre-selected characteristics of the suspension. <IMAGE> Key: 1 = Light source 2 = Detector 15 = Filter AC 4 = Filter DC 5 = Peak detector 6 = Timing device 13 = Holding circuit 7 = Holding circuit 17 = Holding circuit 11 = Input 8 = Control and calculation unit 9 = Indication unit 1 10 = Indication unit 2 14 = Alarm
