Abstract
A pressure sensor assembly having a sensor unit, a pressure port, and an electrical connector. The sensor unit may include a printed circuit board (PCB), a pressure sensor, a support, and a media isolation layer. The PCB may have a first side and an opposite second side, where the pressure sensor may be secured to the first side. The support may also be secured to the first side of the PCB and may circumferentially surround the pressure sensor and/or may define a media sensing opening. The media isolation layer (e.g., a gel or other material) may be provided in the media sensing opening and encase the pressure sensor, where the media isolation layer may transfer a pressure provided by the media in the pressure port to the pressure sensor and may act as a barrier between the media and the pressure sensor.
