SPOR 200 for solar irradiance and flux density measurement

The Pyranometer, used for Solar Irradiance in designed to meet the most demanding requirements for the solar radiation flux density ( W/m2) measurement.

Diagnostic system

Its surface is coated by black coating with high absorption rate.
Hot contacts on the sensors surface, while the cold junction is located within the body.
Temperature difference between the hot and cold junction generates electromotive force, the thermoelectric effect is proportional to the solar radiation.

Solar radiation values(W/m2)= Voltage output value(μV)/sensitivity coefficient (μV*W-1*m2), Each product is with one sensitivity coefficient respectively (It is mentioned on the product’s label)


Solar radiation values(W/m2)=(V/5)*2000(Where V is output voltage value,unit:V )


Solar radiation values(W/m2)=((I-4)/16)*2000(Where I is output current value,unit:mA )

Wind speed sensor

SWOR-01 for wind speed and harsh environments

The SWOR-01 Wind speed sensor is designed for harsh environments, with 304 Anticorrosion stainless steel body and cups. It could be used for wind speed measurement in both PV and Aeolic installations besides a wide variety of other applications, mostly in order to prevent damages in the event of strong winds.

Diagnostic system

The SWOR-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.
Shell is made of high-strength aluminum alloy, the wind cup is made of 304 stainless steel.


PV Trackers.
Wind Turbines.
Cable cars, ropeways & chair lifts.
Telecom towers.



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


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))


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. See the modbus communication protocol specification.
