The invention relates to a transmitter for consistency measuring of pulp suspensions at first hand, comprising a measuring body (1), shaped such as a blade, suspended in a vibration-producing apparatus. The measuring body (1) shaped such as a blade (I' ) shows wave-shaped side surfaces (9, 10) in its transverse direction and is vibratable in a frequency of oscillation between 20-80 Hz and with a predetermined amplitude of +/- 2-8 mm, that provides a combination of both shearing force measurement and a measurement of the resistance of conveyance of liquid through a fibre netting.
L~invention concerne un émetteur permettant de mesurer directement la consistance de pulpes en suspension. L~émetteur comprend un corps de mesure (1) en forme de lame suspendu dans un appareil générateur de vibrations. Le corps de mesure (1) en forme de lame (I') présente des surfaces latérales ondulées (9, 10) dans sa direction transversale et peut être mis en vibration à une fréquence d~oscillation comprise entre 20 et 80 Hz et avec une amplitude prédéterminée de +/- 2 à 8 mm, permettant d~effectuer une mesure simultanée de la force de cisaillement et de la résistance d~écoulement d~un liquide à travers un tissu fibreux.
