1、Rapid Response: The solar radiation sensor is an instrument used to measure the total amount of solar radiation. It employs either the photoelectric effect or the thermoelectric effect to measure the capacity of solar radiation, providing a fast response time of ≤35 seconds. 2、High Accuracy: This radiation sensor can be used in conjunction with various radiation recorders or radiation voltmeters to accurately measure the total solar radiation with an accuracy of ±3%. 3、Wide Measurement Range: With RS485 signal output, DC 9 to 30V power supply, a measurement range of 0 to 2000W/㎡, and a spectral range of 0.3 to 3μm, this sensor offers stability and practicality. 4、Versatile Applications: The solar radiation sensor is commonly used in meteorological observations, monitoring and research of solar power systems, agriculture, aging of building materials, and atmospheric pollution studies. 5、Solar Resource Utilization: By measuring the solar radiation, this sensor provides crucial data for the design and operation of solar energy systems, allowing for better understanding and utilization of solar resources. It serves as an essential tool for solar energy applications. 1 x Solar Radiation Sensor1 x Power Cable Item Type: Solar Radiation SensorMaterial: Stainless Steel, Quartz GlassWeight: Approx. 1464.00g/ 51.64ozPower Supply: DC 9 to 30VProduct Size: Approx. 184x150x84mm/ 7.2x 5.9x 3.3inSignal Output: RS485Sensitivity: 9.394μV▪m/W²Spectral Range: 0.3 to 3μmMeasurement Range: 0 to 2000W/m²Resolution: 1W/m²Accuracy: ±3%Response Time: ≤35 Seconds (99% Response)Internal Resistance: Approximately 286.4ΩNon Linearity Error: ≤±3%Spectral Selectivity: ≤±10%Tilt Response Error: ≤±5%Azimuth Response Error: ≤±30W/m²Temperature Error: ≤±8% (-40℃ to 40℃)Annual Stability: ≤±3%Operating Temperature: -40℃ to +50℃Relative Humidity: 0% to FullApplication: Widely Used in Solar Energy Utilization, Meteorology, Agriculture, Building Material Aging, and Atmospheric Pollution for Measuring Solar Radiation Energy.Product Maintenance 1. Open Or Close The Protective Cover With Special Care, Because The Filter Is Valuable And Fragile. The Filter Should Be Kept Clean And Polished, And Often Wiped With A Soft Cloth Or Fur 2. Water Should Not Be Allowed To Enter The Filter Hood, And There Should Be No Water Vapor Condensation Inside The Hood. To Frequently Check Whether The Desiccant In The Desiccator Becomes Damp (From Orange To Dark Color), Otherwise It Should Be Replaced In Time Or The Desiccant Will Be Taken To The Oven To Bake Dry To Make It Back To Orange Before Use 3. Rainfall (Snow, Ice, Etc.) Or A Longer Period Of Rain, In Order To Protect The Radiation Table, The Observer Should Be According To The Specific Circumstances Of The Best Cover, After The Rain Stops That Is To Open The Cover
