Abstract
A static pressure sensor for sensing the static pressure within a duct regardless of the direction of the air moving through the duct is disclosed having a tube for sensing static pressure, the tube providing an output pressure which is dependent upon the static pressure and a mechanism for permitting the alignment of the tube with respect to the direction of air moving through the duct so that the sensor is direction insensitive to that air.
Claims17
A sensor for sensing the static pressure within a duct regardless of the direction of the air moving through the duct comprising:
- a substantially rigid static pressure tube for sensing static pressure, said static pressure tube having a hollow inside and an aperture therein for connecting the static pressure outside said static pressure tube to its hollow inside, said static pressure tube further having first and second ends;
- output means connected with said static pressure tube intermediate said ends for providing an output pressure dependent upon said static pressure sensed by said static pressure tube, said output means being connected to the hollow inside for receiving said static pressure and having a flexible mounting means for allowing said static pressure tube to align with the air moving through the duct;
- and,
- alignment means associated with said static pressure tube to align said static pressure tube with respect to the air moving through said duct so that said sensor is direction insensitive to said air.
A flow station for sensing the velocity of air moving through a duct which sensor is substantially insensitive to the direction of air moving through said duct comprising:
- a substantially rigid static pressure tube for sensing static pressure, said static pressure tube having a hollow inside and having an aperture therein for connecting the static pressure outside said static pressure tube to its hollow inside, said static pressure tube further having first and second ends;
- output means connected with said static pressure tube intermediate said ends for providing an output pressure dependent upon said static pressure sensed by said static pressure tube, said output means being connected to the hollow inside of said static pressure tube for receiving said static pressure and having a flexible mounting means for allowing said static pressure tube to align with the air moving through the duct;
- alignment means associated with said static pressure tube to align said static pressure tube with respect to the air moving through said duct so that said static pressure tube is direction insensitive to said air;
- and,
- a total pressure sensor substantially insensitive to the direction of air moving through said duct for supplying an output pressure dependent upon the total pressure of said air.
