Abstract

PURPOSE:To provide a wind vane and an anemometer which has no mechanical sliding parts, is robust, and can sample and measure exactly the vector component in one direction of a wind speed without error on account of contamination by converting adynamic air pressure to load by a resistor having a point symmetrical horizontal section and transmitting the same via a connecting bar to differential strain gages. CONSTITUTION:A dynamic air pressure is converted to load by a highly rigid spherica resistor having a point symmetrical horizontal section and the load is transmitted via a connecting bar 2 to the horizontal shaft 4 of a strain converter 3. The transmitted load is differentially detected by strain gages 5a, 5b which have the shape having sensitivity only to the load component in the lateral direction of the shaft 4, are laterally symmetrical and form a Wheatstone bridge. The unidirectional factor component of the wind speed is exactly sampled and measured by such constitution which is robust, and produces no errors by differential measurement owing to contamination.

The output shown in FIG. 2 is given to a load applied horizontally to a point on the shaft 4 via an amplifier. Further, the two strain transducers 3 are coupled in opposite directions and tensioned together on the shaft 4, and a load of approximately % of the operating range is applied to both transducers as a bias. In addition, the output will be taken out in the form of the difference between the strain gauges 5a and 5b, and the relationship between the value converted from the dynamic pressure load of air on the resistor 1 to the shaft 4 and the output is shown in the 31st step 1.

High accuracy. Also, compared to other types of dirt, it has less dirt and is easier to clean. Since the vector properties are good, the error balance due to turbulence is also small. In addition, since there are no sliding parts, errors and failures due to wear are extremely rare. Due to the symmetrical and differential structure principle, there is little drift due to temperature at the zero point.
