Rika RK200-03 Solar Pyranometer Radiation Sensor
PRODUCT DESCRIPTION
Rika RK200-03 Pyranometer is produced based thermopile 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.
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.
