Title (EN) PRESSURE SENSOR
(FR) CAPTEUR DE PRESSION
Abstract: front page image
(EN)A pressure transmitter (10) is provided. The pressure transmitter (10) includes a pressure sensor (60) including a pair of process fluid pressure ports (14, 16) each having a deflectable diaphragm (70, 72). A first variable capacitor is disposed within the pressure sensor (60) and has a capacitance that varies with differential pressure between the process fluid ports (14, 16). A second variable capacitor is disposed within the pressure sensor (60) and has a capacitance that varies with line pressure.
(FR)L'invention propose un transducteur de pression (10). Le transducteur de pression (10) comprend un capteur de pression (60) comprenant une paire d'orifices de pression de fluide de traitement (14, 16) ayant chacun une membrane pouvant être déformée (70, 72). Un premier condensateur variable, disposé à l'intérieur du capteur de pression (60), présente une capacité qui varie avec la pression différentielle entre les orifices de fluide de traitement (14, 16). Un second condensateur variable, disposé à l'intérieur du capteur de pression (60), présente une capacité qui varie avec la pression de ligne.
