This portable power supply instrument for the design
I. Overview:
This portable power supply instrument for the design of three glasses of wire anemometer, apparatus used measurement of SCM technology can measure the instantaneous wind speed at the same time, the average wind speed, wind-instantaneous, and the corresponding average wind-waves, etc. five parameters. Use of the machines the LCD screen customized specifically for the professional and domestic original, which measured parameters and measurement units directly with Chinese characters displayed on the LCD screen, and the survey data shows that the number of high reached 18 MM, more convenient mathematical demonstration of the long-distance observation.
The machines use low-power design and use LCD (LTD), greatly reducing the apparatus of power. Data and a latch function, ease of reading. Machines with small size, light weight, full-function, power consumption provinces, characters , shows that intuitive, easy to carry, and other advantages that can be extensively used in agriculture, forestry, the environment, oceans, in areas such as scientific expedition atmospheric wind measurement parameters. totally natural science teaching in primary and secondary schools can meet the requirements.
Second, the main technical indicators:
1. Wind speed indicators]
(1) wind speed measuring range: 0 to 30 m / sec
(2) wind speed sensor shipment: not more than 0.8 m / sec
(3) wind speed measurement accuracy: error of not more than plus or minus (0.3 plus or minus 0.3 V) m / s (V - actual wind speed)
(4) can show that the wind speed parameters: the instantaneous wind speed, average speed, instantaneous wind level, the average wind level, corresponding waves
(5) Display Resolution: 0.1 m / sec (wind speed) 1 (wind-) 0.1 m (waves)
(6) the functions and units directly with Chinese characters displayed: figures show that high: 18 MM
