Abstract
A pressure sensor capsule includes a capsule body, an isolator, a pressure sensor, and a fluid fill pathway. The capsule body defines a process chamber. The isolator is supported by the capsule body and is exposed to the process chamber. The pressure sensor produces a sensor output that is indicative of a pressure within an interior chamber, which is isolated from the process chamber by the isolator. The fluid fill pathway extends from the process chamber to the interior chamber.
