The sensor FAR61xx is intended for continuous measurements of global radiation (W/m²), that is the sum of the direct solar radiation and the diffuse sky radiation.
The pyranometer measures global solar radiation on a plane/level surface (Watt/m²). The Measured radiation is the sum of direct solar radiation and diffuse sky radiation (global radiation).
PCTRA056 pyranometer is intended for solar radiation measurement on a plane/level surface (Watt/m²). The radiation measured is the sum of direct sun and of diffuse irradiance (global radiation).
The sensor belongs to an economical range of ISO 9060 class C pyranometers for measurement of global solar radiation received by a plane surface, in W/m², from a 180° field of view angle.
The PCTRA055 measures the net radiation across a surface, from near ultraviolet to far infrared. The Net radiation is defined as the difference between the radiation that reaches the upper surface and the irradiation on the lower surface of the net radiometer.
