Combination Wind Vane and Anemometer for Remote Recording (1st Part)

[摘要] A new combination of wind vane and anemometer for remote recording by means of telephone wire was-designed by the authors in the Meteorological Research Institute. As the test experiments had promised a fairly satisfactory performance, the equipment wasinstalled in August 1951 on Yakushima Island, about 60km south of Kyushu.The equipment has a transmitter, with a spring motor wound by the cup-anemometer, and an automatic scanning mechanism for indication of wind vane directions when the spring motor is released at every 200m wind course and rotates at a constant speed controlled by a governor. The wind speed is indicated by the electric pulses generated at every 200m wind course. The transmitter requires no electric energy source, and therefore purely mechanical incorporating electric contacts are required.The signals corresponding to the wind direction and wind speed are sent as electric pulses to the receiver and recorded by means of two helical cams which are started and stopped in synchronization with the effects by a governor of the same characteristics as that of the transmitter.In the 1. part the design and the construction are explained in detail.
