Document Type and Number:
WIPO Patent Application WO/2019/067046
Kind Code:
A8
Abstract:
A pressure sensor capsule (102) includes a capsule body (122), an isolator (124), a pressure sensor (126), and a fluid fill pathway (140). The capsule body defines a process chamber (128). The isolator (124) is supported by the capsule body (122) and is exposed to the process chamber (128). The pressure sensor produces a sensor output that is indicative of a pressure within an interior chamber (130), which is isolated from the process chamber by the isolator (124). The fluid fill pathway extends from the process chamber to the interior chamber.
