AIR_VELOCITY_METER

Uses National LX5600 air temperature reference, connected in unitygain mode, in combination with LX5700 selfheated velocity sensor to convert wind velocity or airspeed to differential between heated and unheated transducers. As wind velocity rises, heating current required to hold velocity sensor predetermined number of degrees above ambientis measured. Calibration curve is drawn to show correlation between current and airspeed.-P.
