Product Description Veinasa-ZFS PV System Used Soar Radiation Sensor Solar PyranometerProduct Description The solar radiation sensor (also called pyranometer) measures solar energy from the sun. Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum. The units of measure are Watts per square meterProduct ParametersPower supplyDC 5V DC 9-30VOther Output signalElectric current4~20mA 0~20mAVoltage0~20mV 0~2.5V 0~5VSerial portRS485(Default Modbus ASCII) RS232(Default Modbus ASCII)Cable lengthStandard:2.5mOtherSensitivity7~14μV?m2/WSpectral range0.3-3μmMeasuring range0~2000W/m2Resolution1W/m2Accuracy±3% of the totalResponse time≤35seconds(99% response)Internal resistanceAbout 250ΩNonlinear error≤±3%Spectral selectivity≤±10%Tilt response error≤±5%Azimuth response error≤±30W/m2Temperature error≤±8% (-40oC~+40oC)Annual stability≤±3%Operating ambient temperature-40oC~+50oCRelative humidity0%~100WeightAbout 2.5kg Product DisplayWhy Measure Solar Radiation? Atmospheric circulation is driven by solar radiation. Determining the solar radiation and its interaction with the atmosphere and the Earth's surface is important, since solar radiation accounts for almost all of the energy available to the Earth. There are ways solar radiation reaches the Earth's surface. The first is direct solar radiation where the solar radiation is directly transmitted through the atmosphere. The second is diffuse solar radiation where the incoming solar radiation is scattered or reflected to the Earth's surface. Almost 50% of shortwave solar radiation is absorbed by the Earth's surface and changed into thermal infrared radiation. Direct solar radiation is measured by using solar radiation sensors or pyranometers. These type of solar radiation sensors have a transparent hemisphere which measures the total amount of shortwave solar radiation. Solar radiation sensors or pyranometers measure the total radiation or sum of the direct radiation and the diffuse solar radiation.Application case Company Profile FAQPackaging & Shipping
