Title (EN) THROUGH AIR RADAR LEVEL TRANSMITTER WITH RADIO FREQUENCY SHIELDING
(FR) ÉMETTEUR DE NIVEAU À RADAR À AIR TRAVERSANT AVEC BLINDAGE RADIOFRÉQUENCE
Abstract:
(EN) A through air measurement instrument comprises a housing for mounting to a process vessel and including a waveguide, A control circuit in the housing controls operation of the instrument for determining level, An RF circuit board in the housing is operatively controlled by the control circuit and includes a microwave transceiver circuit connected via a coupler to strip line traces on the printed circuit board for coupling a high frequency radar signal with the waveguide for measuring level, A multi-function RF shield comprises a cover for the RF circuit board. The cover includes a metallic covering on an inside surface for capping the waveguide and providing an RF shield.
(FR) L'invention concerne un instrument de mesure à air traversant comprenant un boîtier destiné à être monté sur un récipient de traitement et comprenant un guide d'ondes, un circuit de commande dans le boîtier commande le fonctionnement de l'instrument pour déterminer le niveau, une carte de circuit imprimé RF dans le boîtier est commandée de manière fonctionnelle par le circuit de commande et comprend un circuit émetteur-récepteur de micro-ondes connecté par l'intermédiaire d'un coupleur à des traces de ligne de microplaquette sur la carte de circuit imprimé pour coupler un signal radar haute fréquence au guide d'ondes pour mesurer le niveau, un blindage RF multifonction comprend un couvercle pour la carte de circuit imprimé RF. Le couvercle comprend un revêtement métallique sur une surface intérieure pour recouvrir le guide d'ondes et fournir un blindage RF.
