Abstract
An electronic pressure sensor includes a housing having a distal end configured to be exposed to a flow of a fluid media, the distal end opposite a proximal end, wherein the proximal end is configured not to be exposed to the fluid media. A chamber and connected passageway are disposed within the housing. The passageway is connected at one end to the chamber and connected at another end to an opening disposed at the distal end of the housing. The opening is configured to be in fluidic communication with the fluid media. A pressure sensor is disposed within the chamber. A first temperature sensor is disposed within the chamber. A viscous gel is disposed within the chamber, the viscous gel separating on a first side both the pressure sensor and the first temperature sensor apart from the passageway on a second side of the viscous gel.
