QS-FX 360 degree wind sensor
⊙Texture of material
The use of carbon materials, with rain, corrosion, anti-aging, durable and other advantages
⊙Application scope
The sensor can be measured in outdoor environment can be measured by the north wind, the label as the starting point of the 0-360 of natural wind, has a very high price. This instrument is widely used in environmental protection, meteorology, agriculture, forestry, water conservancy, construction, field research and teaching。
⊙Functional characteristics
◆The utility model has the advantages of small size, light weight, convenient carrying and installation in the field, and waterproof and shockproof structure
The utility model can be used in the field all day
◆The system has the advantages of high precision, low power consumption, environmental protection and energy saving design
◆Wide range, good stability
◆The data showed good linearity, long transmission distance and strong ability to resist external interference
⊙Fixed mode
The flange mounting method, threaded flange connection enables the direction sensor fittings firmly fixed on the lower flange on the chassis with 66mm, 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 wind data flange connection, easy to use, able to withstand greater pressure. The following, please note: in the installation must be upright arrow at North (actually available to assist the compass) so below, black wind sensor affixed with black white and white arrow labels; with wind direction sensor Red arrow。
⊙technical parameter
Measuring range: 0–360 degrees
Load capacity:Less than 600 Ω, the general recomm 250Ω
▲ Voltage type:
input voltage: 7V~24V DC
output signal:0.4~2V(
Wind direction = (output voltage -0.4) /16*360
▲ Current type:
input voltage:12V~24 V DC output signal: 4~20mA
Wind direction = (output current -4) /16*360
▲ 485type:
input voltage:7V~24 V DC
communication protocol:The wind direction sensor uses the standard Modbus communication protocol,Can be used to read the direction of the wind number 03 (Note: default 2 station)
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)。
3C 27:CRC check value
