RK200-03T Class A Pyranometer
PRODUCT DESCRIPTION
rk200-03 Pyranometer is produced based on the thermopile principle;sensing elements are made bywound plated thermopiles with muttsple contacts.Its surface is coated by black coating with highabsorption 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 an electromotive force,thethermoelectric effect is proportional to the solar radiation.In order to reduce the ambient temperatureeffect,temperature compensation circuit designed here to minmize its impact on the product'sperformance.The RK200-03 series pyranometer has been certified by the National MeteorologicalAdministration and the National Institute of Metrology(NIM).
The pyranometer radiation sensor is a monitoring device designed to accurately measure solar radiation levels. As an essential component for meteorological and climatological research, this sensor plays a pivotal role in analyzing the energy balance of our planet. Equipped with advanced technology, the pyranometer sensor precisely quantifies the total hemispherical solar irradiance by capturing both direct and diffuse radiation. Its robust construction ensures long-term durability even under harsh environmental conditions, making it suitable for various applications such as weather stations, solar energy installations, and agricultural monitoring systems. With its high sensitivity and low thermal offset, this radiation sensor provides reliable measurements that are vital for understanding climate patterns and optimizing renewable energy sources. The pyranometer radiation sensor is indeed an indispensable tool serving scientists, researchers, and engineers alike in their pursuit of sustainable solutions while unraveling the mysteries of our ever-changing world.

OUTPUT CHARACTERISTICS
● 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 )
● 4-20 mA
Solar radiation values(W/m2)=((I-4)/16)*2000(Where I is output current value,unit:mA )
● RS485
MODBUS-RTU
MOUNTING & MAINTENANCE
● The sensor should be installed in the open air without any shield above the sensing surface,items
should be avoided from being placed between the path of sunlight and the instrument to prevent
shadows from appearing on the instrument.
● Horizontal installation should adjust the horizontal position before fixing the sensor.
● It can be installed tilted or inverted as needed to measure tilted radiation or ground reflection
radiation,When installed upside down, WMO recommends mounting it at least 1.5m above the ground.
Please check the glass dome regularly & make sure itis clean.
● Please do not remove or loose the glass dome,otherwise the accuracy will be affected.
● Please make sure the desiccant to be dry .(If the desiccant changes color, replaced it immediately
recommended to replace the desiccant every 6 month.)
Protection cover is not necessary in general rainfall, but if prolonged heavy rains or hail, the protective
cover is recommended to be installed.
● The sensitivity is recommended to be re-calibrated after two years use.
