Title (EN) PRESSURE SENSOR HAVING COPLANAR METER BODY WITH SENSOR OVERPRESSURE PROTECTION
(FR) CAPTEUR DE PRESSION PRÉSENTANT UN CORPS DE COMPTEUR COPLANAIRE DOTÉ D'UNE PROTECTION DU CAPTEUR CONTRE LA SURPRESSION
Abstract:
(EN) An apparatus includes a sensor body (206) and a sensor (204) configured to measure differential pressure. The apparatus also includes first and second coplanar pressure inputs in or on the sensor body, where 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. First and second fill fluid (406, 408) may be configured to convey the pressures from the barrier diaphragms of the pressure inputs to the sensor as first and second input pressures. Passages (212, 402, 404) may be configured to transport the fill fluid between (i) gaps between the barrier diaphragms and the overload diaphragms of the pressure inputs and (ii) the sensor and gaps between the overload diaphragms and the sensor body.
(FR) La présente invention concerne un appareil comprenant un corps de capteur (206) et un capteur (204) conçu pour mesurer une pression différentielle. L'appareil comprend également des première et seconde entrées de pression coplanaires dans le corps de capteur ou sur le corps de capteur, les entrées de pression étant 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 mouvement du diaphragme barrière. Des premier et second fluides de remplissage (406, 408) peuvent être conçus pour acheminer les pressions des diaphragmes barrières des entrées de pression au capteur en tant que première et seconde pressions d'entrée. Des passages (212, 402, 404) peuvent être conçus pour transporter le fluide de remplissage entre (i) des espaces entre les diaphragmes barrières et les diaphragmes de surcharge des entrées de pression et (ii) le capteur et les espaces entre les diaphragmes de surcharge et le corps de capteur.
