QS-FS Wind sensor
⊙Exterior specification
Compact and lightweight, easy to carry and assembly, three cup
design concept can effectively obtain external environmental information
⊙Texture of material
Mainly uses the high quality polymer carbon fiber as raw material, has excellent corrosion resistance, anti erosion and other characteristics, to ensure the long-term use of instruments not rust, at the same time with the smooth internal sliding bearing system, to ensure the accuracy of the information collection.
⊙Application scope
The utility model can be widely applied to the measurement of the wind speed in the greenhouse, the environmental protection, the meteorological station, the ship, the wharf, the culture and the like。
⊙Functional characteristics
◆ Small size, easy to carry, easy installation
◆ High measuring accuracy, wide range, good stability
◆ Reasonable structural design, good appearance quality
◆ The linearity of the data information is good, the signal transmission distance is long, and the ability to resist external interference is strong
⊙Fixed mode
The flange mounting method, threaded flange connection enables the direction sensor fittings firmly fixed on the lower flange on the chassis with 65mm, four were mounting holes in the circumferential Phi 6mm Phi 50mm on the use of bolts securely fixed on the bracket, the whole set of instrument is maintained at an optimum level,To ensure the accuracy of the wind direction data, flange connection is easy to use, can withstand greater pressure

Communication protocol: the wind speed sensor adopts the standard Modbus communication protocol,
Can be used to read the wind speed number 03 (Note:station number 2 default)
Send data command format:
02 03 00 00 00 01 84 39
02:Equipment station number
03:Command number, used in standard Modbus protocol to read data from memory
00 00:Read data start address,Wind speed value in memory 0000 Start address。
00 01:Read the number of data, the wind speed value in the memory of a data space, Modbus, a data space occupies 2 bytes of space。
84 39:CRCCheck value
Receive command format parsing:
02 03 02 01 45 3C 27
02:Equipment station number。
03:Command number
02:Return data length
01 45:Returnwindspeedvalue,InModbus,thehigh8bitsof data are in the first place, and the lower 8 bits in the behind,so (Wind speed value = wind return value /10, wind speed return value =0145,According to the actual value of the user can calculate the value of wind speed, where the figures are 16)。
