Abstract

An example coupling mechanism for a media-isolated pressure sensor, method for manufacturing the coupling mechanism, and media-isolated pressure sensor are provided. The coupling mechanism includes a fluid coupling medium disposed in an interior cavity of a pressure sensor housing, forming a barrier between pressure sensing circuitry and a fluid. Disposing the fluid coupling medium includes dispensing within the interior cavity, a first portion of a fluid coupling substance having a volume less than a maximum substance volume, and removing dissolved gas from within the first portion. Disposing the fluid coupling medium further includes dispensing a second portion of the fluid coupling substance within the interior cavity, the second portion also having a volume less than the maximum substance volume. The fluid coupling substance is cured, forming a coupling mechanism, such that pressure sensing circuitry generates electrical signals based on pressure imposed by the fluid through the coupling mechanism.
