Abstract
An electronic sensor includes a housing having a distal end configured to be exposed to a flow of a fluid media opposite a proximal end 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 and a first temperature sensor are 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. The chamber can include a non-smooth surface to increase viscous gel adhesion.
