The RK100-01 Wind Speed Sensor is specifically designed to accurately and reliably measure wind velocity under the adverse environmental conditions.Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are build-in,it output voltage and current signals by electromagnetic induction, The value and horizontal wind speed are linear relation.Shell is made of high-strength aluminum alloy, the wind cup is made of 304 stainless steel, the PCB board is painted with anti-corrosion coating, featured with water proof, corrosion resisting. Inside and turning position have sealing rings with nice sealing function, stop water, salt fog and dust getting in.The RK100-01 Wind speed sensor has good performance in harsh environment.

OUTPUT CHARACTERISTICS
Pulses
Characteristic transfer function:
V=0.667*F
(where V = wind speed (m/s),F = output frequency(Hz))

Current

Voltage
Characteristic transfer function:
V=U/( full scale voltage-zero point voltage)*30(Range:0-30m/s),
V=U/( full scale voltage-zero point voltage)*60(Range:0-60m/s).
(where V = wind speed (m/s),U = output voltage(V))
RS485
If the transmission distance is over 100m, please add a 120Ω terminal matching resistances on the front end and back end of bus interface respectively.Please refer to the modbus communication protocol specification.
DIMENSION & MOUNTING
Flange mounted, fix four screws on the bracket and keep the product horizontal.

It is recommended to use 0-30m/s range, which can get a better measurement accuracy. More than 30m/s wind is rare on mainland;
The default power supply voltage is 12-24VCD,if you have other requirements please confirm when ordering.
Example: RK100-01AA1500 Output:4-20mA,Range:0-30m/s,Cable Length:1.5m.
