Albedometers (Reflectivity Sensor) RK200-14
SKU: WTH-00479
Available
Easy installation
Overview
RK200-14 Albedometers is used to measure the reflectivity of earth objects to solar radiation. It needs to be installed horizontally in an open area with no obstacles above the sensing surface. The RK200-14 Albedometers is based on the principle of pyroelectric effect. The sensing element adopts a wire-wound electroplating multi-contact thermopile, and its surface is coated with a black coating with high absorptivity. The hot junction is on the sensing surface, and the cold junction is located in the body, and the hot and cold junctions generate a thermoelectric potential. In the linear range, the output signal is proportional to the solar radiation value.
