Title (EN) CAPACITANCE-TO-DIGITAL MODULATOR WITH SENSOR FAILURE-MODE DETECTION
(FR) MODULATEUR DU NUMÉRISEUR DE CAPACITÉS AVEC DÉTECTION DU MODE DÉFAILLANCE DE LA SONDE
Abstract: front page image
(EN)A pressure transmitter having a capacitance-to-digital modulator produces an output as a function of a ratio sensor capacitance and a reference capacitance. Transmitter also includes a sensor failure mode detector produces an output signal and identifies failure modes of the sensor capacitance and reference capacitance.
(FR)Un transmetteur de pression possédant un modulateur de numériseur de capacités produit une sortie en fonction d'un rapport capacitance de sonde et capacitance de référence. Le transmetteur comprend également un détecteur de mode de défaillance de sonde qui génère un signal de sortie et identifie des modes de défaillance de la capacitance de sonde et de la capcitance de référence.
