摘要： A capacitive pressure transmitter is provided. In one aspect, the transmitter includes a capacitive pressure sensor coupled directly to the measured media without any intervening fluid isolation. A filter is preferably used to keep particulates from reaching the measuring diaphragm. In another aspect, a capacitive pressure transmitter is provided with at least one self-contained isolator interposed between a process connection and the capacitive pressure sensor. In both aspects, the capacitive pressure transmitter is relatively small and preferably constructed from materials that facilitate low-cost manufacture.

摘要翻译： 提供电容式压力变送器。在一个方面，发射机包括直接耦合到测量介质的电容式压力传感器，而没有任何中间的流体隔离。优选使用过滤器来保持微粒到达测量隔膜。在另一方面，电容式压力变送器设置有插入在过程连接和电容式压力传感器之间的至少一个独立的隔离器。在两个方面，电容式压力变送器相对较小，并且优选地由便于低成本制造的材料构成。

摘要： A pressure transmitter with a fluid isolator that includes a sensor tube and a fill tube that have “D” shaped ends that connect together in a port internal to the transmitter. The shaped ends can be brazed into the port for sealing. Fitting both the sensor tube and the fill tube in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator has an isolator diaphragm with a central diaphragm region overlying a central backing plate that includes a annular groove. The annular groove avoids slow response of the isolator after an overpressure condition.
