Abstract: Druckwandler (10, 82) mit einem verbesserten Isolatorsystem mit: einem Wandlerkörper (12, 84) mit einer äußeren Isolatoreinfassung (14) um eine geformte Konkavität (16, 88), die in Flüssigkeitskopplung mit einem gemeinsamen Anschluß (18, 90) innerhalb des Wandlers (10, 82) über einen Durchgang (20, 22, 92) durch den Körper steht, wobei die Konkavität (16, 88) einen mittleren Trägerplattenbereich (24, 94) hat; einer Isolatormembran (26, 96) mit einer Membraneinfassung (28), die an der Isolatoreinfassung (14) abgedichtet ist und einen mittleren Membranbereich (30, 100) hat, der aber dem mittleren Trägerplattenbereich (24, 94) liegt und von diesem beabstandet ist; Isolatorflüssigkeit (32) zwischen der Isolatormembran (26, 96) und der geformten Konkavität (16, 88) sowie im Durchgang (20, 22, 92); einem Drucksensor (36, 104), der Druck vom Anschluß (18) über eine Sensorröhre (38, 107) mit einem im gemeinsamen Anschluß (18) angeordneten ersten geformten Ende (40, 108) empfängt, wobei der Sensor (36, 104) eine Druckausgabe (106) erzeugt; einer Füllröhre (50, 109), die innerhalb des Wandlers (10, 82) liegt und geeignet ist, den Isolator abzudichten, wobei die Füllröhre (50, 109) ein im gemeinsamen ...

Abstract: A pressure transmitter (10) with a fluid isolator (11) that includes a sensor tube (38) and a fill tube (50) that have "D" shaped ends (40, 54) that connect together in a port (18) internal to the transmitter (10). The shaped ends (40, 54) can be brazed into the port (18) for sealing. Fitting both the sensor tube (38) and the fill tube (50) in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator (11) has an isolator diaphragm (96) with a central diaphragm region (100) overlying a central backing plate (94) that includes an annular groove (111). The annular groove (111) avoids slow response of the isolator (11) after an overpressure condition.
Abstract translation: 一种具有流体隔离器(11)的压力变送器(10),其包括传感器管(38)和填充管(50),所述传感器管(38)和填充管(50)具有在内部端口(18)中连接在一起的“D”形端 到发射机(10)。 成形端部(40,45)可以钎焊到端口(18)中用于密封。 将传感器管(38)和填充管(50)同时配合在同一个端口,提供了一种具有降低的隔离液体积的低成本隔离器。 流体隔离器(11)具有隔离隔膜(96),其中央隔膜区域(100)覆盖在包括环形凹槽(111)的中央背板(94)上。 环形槽(111)避免了超压状态后隔离器(11)的响应缓慢。
