Abstract
The invention comprises an improved sensing instrument (10) for sensing the angular position of the longitudinal axis (17) of a cylindrical sensor body (14) of an object moving relative to a fluid medium with respect to a first plane. Such object has a leading end portion (15) joined to the sensor body (14) and exposed to the fluid medium. A first pair of pressure sensing ports (20 and 21) are on the object and face in the upstream direction and have their axes lying in a second plane at right angles to said first plane and disposed at predetermined angles with respect to the axis (17) of the object. A second pair of pressure sensing ports (22 and 23) on the object have their axes lying in the first plane, such axes being disposed at predetermined angles with respect to the axis (17) of the object. A single pressure port (16) on the object has an axis coinciding with the axis (17) of the object. The improvement comprises the leading end portion ( 15) of the sensor body (14) defining a spherical segment of one base.
