An apparatus for obtaining pressure measurements in an airstream includes a Pitot tube. The Pitot tube includes at least one total pressure port configured to be positioned in the airstream facing upstream, at least one static pressure port configured to be positioned in the airstream facing downstream, at least one first directional port, and at least one second directional port. The at least one first directional port and the at least one second directional port are positioned on opposite sides of the at least one total pressure port and face obliquely with respect to the direction that the at least one total pressure port faces.
A pressure sensor includes a housing, a pressure chamber defined within the housing, and a pressure transducer. The pressure sensor also includes a header that seals the pressure chamber and supports the pressure transducer in the pressure chamber. A plurality of pins extend through respective openings in the header. The sensor pins have first ends electrically connected to the pressure transducer in the pressure chamber and second ends electrically connected to sensor electronics outside the pressure chamber. The pins are electrically insulated from the header. The header is configured so that the electrical insulation of at least one pin from the header is less than the electrical insulation of the remaining pins from the header.

A pressure gage adapted to provide a mechanical indication of a sensed pressure and to provide an electrical signal indicative of the sensed pressure. The pressure gage includes a housing having a first fluid pressure chamber, a second fluid pressure chamber, and flexible diaphragm separating the first fluid pressure chamber from the second fluid pressure chamber. A magnet is coupled to the diaphragm such that movement of the diaphragm causes a related movement of the magnet. A helix is located adjacent to the magnet and a pointer is attached to the helix for conjoint rotation with a helix about a rotational axis. A Hall effect sensor is also located adjacent the magnet. Movement of the magnet in response to movement of the diaphragm rotates the helix and the pointer to provide a mechanical indication of the pressure sensed by the diaphragm, and the movement of the magnet causes the Hall effect sensor to generate an electrical signal indicative of the pressure sensed by the diaphragm.
