Title
(EN) INTEGRATED ACOUSTIC EMISSION TRANSDUCER APPARATUS AND METHOD
(FR) PROCÉDÉ ET APPAREIL TRANSDUCTEUR D'ÉMISSION ACOUSTIQUE INTÉGRÉ
Abstract
(EN)
Integrated acoustic emission transducer apparatus and methods are described. An example apparatus includes an acoustic emission sensor having a data extractor and a process variable determiner integrated within the acoustic emission sensor. The acoustic emission sensor is to generate an acoustic emission signal. The data extractor is to extract signal data from the acoustic emission signal. The process variable determiner is to determine process variable data based on the extracted signal data. The process variable data includes at least one of leakage rate data, flow rate data, flow capacity data, flow area data, flow velocity data, mass accumulation data, or volume accumulation data.

L'invention concerne des procédés et un appareil transducteur d'émission acoustique intégré. Un appareil donné à titre d'exemple comprend un capteur d'émission acoustique possédant un extracteur de données et un dispositif de détermination de variables de processus intégré dans le capteur d'émission acoustique. Le capteur d'émission acoustique est destiné à générer un signal d'émission acoustique. L'extracteur de données est destiné à extraire des données de signal du signal d'émission acoustique. Le dispositif de détermination de variables de processus est destiné à déterminer des données de variable de processus en fonction des données de signal extraites. Les données de variables de processus comprennent des données de taux de fuite, des données de débit, des données de capacité d'écoulement, des données de zone d'écoulement, des données de vitesse d'écoulement, des données d'accumulation de masse et/ou des données d'accumulation de volume.
