Abstract

Embodiments relate generally to methods and systems for detecting pressure. A pressure sensor assembly may comprise a sensor unit having a pressure input port on one side, the sensor unit comprising a printed circuit board; a pressure sensor secured to a side of the printed circuit board; a support secured to the side of the printed circuit board, the support circumferentially surrounding the pressure sensor and defining the pressure input port; and a media isolation layer comprising a first media isolation layer applied adjacent to the pressure sensor, and a second media isolation layer comprising a material different from the first media isolation layer located between the first media isolation layer and the pressure input port, wherein the media isolation layer is configured to transfer a pressure caused by a sense media to the pressure sensor.
