Title
(EN) MEASURING APPARATUS
(FR) APPAREILLAGE DE MESURE
Abstract
(EN)
Apparatus for measurement concerning fluids in a rotor or container (2) during rotation, comprising an electric or magnetic sensor (4) mounted internally on a wall in the container (2), and means (5A, 5B) for contact-free and intermittent transmission of measurement signals from the sensor (4) to a stationary measuring unit (7) outside the container. The sensor (4) comprises an active electronic circuit (8) adapted to store measurement values that are recorded during at least a portion of a revolution of the container (2), before said transmission of corresponding measurement signals to the measuring unit (7). Electric power supply to the electronic circuit (8) is provided for by generator means comprising a stationary magnet (11) near the container (2) and a coil (12) mounted in the container so that a voltage is induced in the coil (12) during movement past the magnet (11) during the rotation of the container (2).
(FR)
L'invention porte sur un appareillage de mesure concernant des fluides dans un rotor ou un condenseur (2) durant une rotation. Cet appareillage comporte un détecteur électrique ou magnétique (4) monté sur la paroi interne d'un conteneur (2) et des organes (5A, 5B) destinés à assurer une transmission sans contact et intermittente de signaux de mesure en provenance du détecteur et à destination d'un poste stationnaire de mesure (7) se trouvant en dehors du conteneur. Le détecteur (4) comprend un circuit électronique actif (8) à même de mémoriser des valeurs de mesure enregistrées durant au moins une partie de révolution du conteneur (2) avant ladite transmission des signaux de mesure correspondants à l'unité de mesure (7). Un générateur, qui approvisionne en énergie électrique le circuit électronique (8), est constitué d'un aimant stationnaire (11) près du conteneur (2) et d'une bobine (12) montée sur le conteneur de sorte qu'une tension est induite dans celle-ci au cours du déplacement effectué devant l'aimant (11) par la rotation du conteneur (12).
