SOLAR RADIATION SENSOR
RY-EBN-1
MANUAL
INTRODUCTION
RY-EBN-1 is mainly used to measure the solar short wave radiation in the wavelength range of 400-1100nm. It is simple and cost-effective, and can be used continuously all day long, and can be inverted or tilted. It is widely used in solar energy monitoring of plant growth, soil water evaporation and transpiration loss in heat transfer box.
Typical applications: ecological radiation monitoring of agriculture and forestry, research on solar thermal utilization
Tourism environmental protection ecology, agrometeorological research, crop growth monitoring, greenhouse control.
PRINCIPLE
RY-EBN-1 is used to measure the short wave radiation of the sun. It uses a silicon light detector to produce a voltage output signal proportional to the incident light. In order to reduce cosine error, a cosine corrector is installed in the instrument. The sensor can be directly connected with a digital voltmeter or a digital collector to measure the radiation intensity. The unit of output is w · m-2. Output radiation (w · m-2) = measured output voltage signal value (μ V) ÷ sensitivity coefficient (μ V · W-1 · m2), each radiometer gives its own sensitivity coefficient.
