US07827866B2 Pressure transducer and method for monitoring the state of a pressure transducer and pressure sensor 有权
用于监测压力传感器和压力传感器状态的压力传感器和方法

Pressure transducer and method for monitoring the state of a pressure transducer and pressure sensor
Abstract:
A pressure transducer for a pressure sensor (2) for determining at least one pressure (pa, pb) in a process media (3a, 3b) has a housing (4) with a separating diaphragm (5a, 5b), at least one first pressure-sensing element (6a, 6b), a contact media (7a, 7b), at least one first connection element (8a, 8b) and at least one first seal (9a, 9b). The separating diaphragm (5a, 5b) separates the process media (3a, 3b) from the contact media (7a, 7b), the contact media (7a, 7b) conveys the pressure (pa, pb) of the process media (3a, 3b) determined by the separating diaphragm (5a, 5b) to the first pressure-sensing element (6a, 6b). The first seal (9a, 9b) houses the first connection element (8a, 8b) and the housing (4), the separating diaphragm (5a, 5b) and the first seal (9a, 9b) form a first pressure chamber (10a, 10b). A second pressure chamber (14) is provided on the side of the first pressure chamber (10a, 10b) opposite the first seal (9a, 9b) and a second pressure-sensing element (15) is arranged in the second pressure chamber (14).
Abstract(Chinese):

用于确定处理介质（3a，3b）中的至少一个压力（pa，pb）的压力传感器（2）的压力传感器具有带有隔离膜（5a，5b）的壳体（4），至少一个第一 压力感测元件（6a，6b），接触介质（7a，7b），至少一个第一连接元件（8a，8b）和至少一个第一密封件（9a，9b）。 分离膜（5a，5b）将处理介质（3a，3b）与接触介质（7a，7b）分离，接触介质（7a，7b）将处理介质（3a，7b）的压力（pa，pb） 3b）由分离膜（5a，5b）确定到第一压力感测元件（6a，6b）。 第一密封件（9a，9b）容纳第一连接元件（8a，8b）和壳体（4），隔离膜（5a，5b）和第一密封件（9a，9b）形成第一压力室 10b）。 第二压力室（14）设置在第一压力室（10a，10b）的与第一密封件（9a，9b）相对的一侧，第二压力感测元件（15）设置在第二压力室 ）。
