Abstract

PURPOSE:To permit a highly accurate and stable wind velocity measurement by equipping a wind velocity oscillating device with a power supply device and an operation amplifier, etc., thereby to enable the device to issue an output signal. CONSTITUTION:AC voltage is given to power supply devices 25 and 26 from terminals P1 and P2 of a synchro electric applicance 32 through a transformer 33, and DC output voltage of the device 25 is impressed onto LED and D through a current controller R4 to turn them on and off, and then, radiant light is applied to a reflector 22 for oscillation of wind velocity pulse. By doing so, pulse-shaped radiant light is made to enter a phototransistor TR for photoelectric conversion, and then, it is put into an operation amplifier 27. By this input to the operator 27, when the transistor TR is ON, an input terminal 28 becomes lower than an input terminal 29 providing a relationship of output V0<+V0<->. When the transistor TR is OFF, the terminal 28 becomes higher than the terminal 29 providing a relationship of V0<+>>V0<->. In short, the output V0<+> becomes an inversion pulse with plus and minus approx. VDD, and as output impedance of the amplifier 27 is low, average level of the output V<+> always becomes zero volt, and therefore, it become possible simply by judging the symbol of input signal.
