Abstract
A pressure sensing device with a tubular pressure port including an internal chamfer adjacent to a deflectable diaphragm, and/or a hydrophobic or superhydrophobic coating applied to at least a portion of the tubular pressure port, the internal chamfer, and/or the deflectable diaphragm. The internal chamfer and/or the hydrophobic or superhydrophobic coating are configured at least in part to reduce adhesive forces between condensation and the surface of the tubular pressure port, to reduce the tendency for capillary action to draw condensation towards the deflectable diaphragm, and/or to increase the tendency for capillary action or gravity to draw condensation away from the deflectable diaphragm and out of the tubular pressure port.
