Description

The RK200-03 Pyranometer is produced based thermoelectric principle; sensing elements are made by winding - plated thermopiles with multi contacts.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. In order to reduce the ambient temperature effect ,temperature compensation circuit designed here to reduce the effects to products properties.

①If you choose to 0-20 mv signal output, without power supply.
②If you choose to RS485 output signal, the need to increase the external signal conversion module(98*66*49mm).

Output Characteristic
  • 0-20mV
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)
  • 0-5V
Solar radiation values(W/m2)=(V/5)*2000(Where V is output voltage value,unit:V )
  • 4-20mA
Solar radiation values(W/m2)=(I-4)/16*2000(Where V is output current value,unit:mA )
  • RS485
MODBUS-RTU
