PURPOSE:To record a wind whose variation is quick, easily and exactly, by deciding the maximum value and the minimum value as to each wind direction and wind velocity from an instantaneous wind sigal at every interval time, and recording them. CONSTITUTION:An instantaneous wind signal from a sensible part 11 responding to a wind direction and a wind velocity is sampled by an interface 12 and a microcomputer 13, and the computer 13 calculates the maximum value and the minimum value as to wind direction and a wind velocity of every prescribed interval time. These values are recorded intermittently on recording paper at every interval through a pen raising mechanism 17 controlled at every interval time through the computer 13, a recording paper feed motor 16, etc. By this intermittent recording, a wind whose variation is quick can also be recorded easily and exactly. In this regard, when the mode is switched by a mode switch 14, a mean value, etc. within the interval can be recorded, as well. |
