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.
