Title (EN) PRESSURE SENSOR HAVING OVERPRESSURE PROTECTION WITH REDUCED OUTPUT ERROR
(FR) CAPTEUR DE PRESSION PRÉSENTANT UNE PROTECTION CONTRE LES SURPRESSIONS À ERREUR DE SORTIE RÉDUITE
Abstract:
(EN) An apparatus includes a sensor body (206), a sensor (204) configured to measure differential pressure, and first and second pressure inputs in or on the sensor body. The pressure inputs are configured to provide multiple input pressures to the sensor. Each pressure input includes a barrier diaphragm (208, 210) configured to move in response to pressure and an overload diaphragm (216, 218) configured to limit movement of the barrier diaphragm. The overload diaphragm is also configured to exert a preload force against the sensor body. The overload diaphragm of each pressure input may include multiple convolutions. Bases (502) of the convolutions may be configured to provide the preload force, and tops of the convolutions may be separated from the sensor body by gaps (504). Tops (602) of the convolutions that are non-adjacent may be configured to provide the preload force, and tops of the convolutions between the non-adjacent convolutions may be separated from the sensor body by gaps (604).
(FR) L'invention concerne un appareil qui comprend un corps de capteur (206), un capteur (204) conçu pour mesurer une pression différentielle, et des première et seconde entrées de pression dans ou sur le corps de capteur. Les entrées de pression sont conçues pour fournir de multiples pressions d'entrée au capteur. Chaque entrée de pression comprend un diaphragme barrière (208, 210) conçu pour se déplacer en réponse à une pression et un diaphragme de surcharge (216, 218) conçu pour limiter le déplacement du diaphragme barrière. Le diaphragme de surcharge est également conçu pour exercer une force de précharge contre le corps de capteur. Le diaphragme de surcharge de chaque entrée de pression peut comprendre de multiples convolutions. Des bases (502) des convolutions peuvent être conçues pour fournir la force de précharge, et des sommets des convolutions peuvent être séparés du corps de capteur par des entrefers (504). Des sommets (602) des convolutions non adjacentes peuvent être conçus pour fournir la force de précharge, et des sommets des convolutions entre les convolutions non adjacentes peuvent être séparés du corps de capteur par des entrefers (604).
