  • Product Name: RK100-01 Wind Speed Sensor

The RK100-01 Wind Speed Sensor is specifically designed to accurately and reliably measure wind velocity under the adverse environmental conditions. Build-in Digital circuits are capable of strong RFI & EMI resistance and automatic temperature compensation. Voltage and current signals output by electromagnetic induction, generate a linear relation between acquired values and horizontal wind speed .The sensor mainly includes high-strength aluminum-alloy housing shell, 304SS wind cup, PCB board painted with anti-corrosion coating, and features water proof and corrosion resistance. The sealing rings are used to wrap the rotating part, with the excellent sealing function of water proof, salt fog and dust immersing. RK100-01 Wind speed sensor has good performance in harsh environment.

OUTPUT CHARACTERISTICS

Pulses
Characteristic transfer function:
V=0.667*F(Range:0-30m/s),            
V=1.333*F(Range:0-60m/s).     
(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.

0-30m/s range is recommended,which can get a better measurement accuracy.( > 30m/s wind is rare on mainland);
The default power supply voltage is 12-24VDC,if you have other requirements please confirm when ordering.
If you need wireless output, please contact us, we will provide professional solutions.
Example: RK100-01AA1500   Output:4-20mA,Range:0-30m/s,Cable Length:1.5m.
